Basic procedures for choosing cell seeding densities

To effectively examine metabolic and bioenergetic function using your Agilent Seahorse Extracellular Flux Analyzer, it is essential to first characterize a specific cell type with respect to its metabolic activity under basal and maximal respiration (OCR) and extracellular acidification (ECAR). The Seahorse XF Real-Time ATP rate assay Test Kit The Seahorse XFp Real-Time ATP rate assay Test Kit The Seahorse Cell Energy Phenotype Test Kit can be used to characterize the cell line/type of interest in a single assay. two short assays.

Optimal cell seeding number varies by cell type, but is typically between 5 x 10³ and 4 x 10⁴ cells per well. 1 x 10⁴ and 8 x 10⁴ cells per well. Generally, densities resulting in 50-90% confluency generate metabolic rates in the desirable/dynamic range of the instrument.

Please consult the Seahorse Cell Reference Database and/or the XF Publication database to provide an initial starting point for cell density values specific to your needs.

Seeding Cells

Basic procedures for seeding adherent cells (typically performed the day before the XFp assay)

For each density to be tested, seed as directed for adherent cells. View instructions for seeding suspension cells.

Agilent Seahorse XFp Assays are performed in an Agilent Seahorse 96-well 24-well 8-well XFp Cell Culture Microplate Miniplate in conjunction with an XFe96 Sensor Cartridge. This procedure describes recommendations for seeding adherent cell types for use with the Agilent Seahorse Analyzer. View instructions for seeding suspension cells.

A method for four different cell densities using an XF96 cell culture plate, XFe96 cartridge and the Seahorse XF Real-Time ATP rate assay kit with an instrument is recommended for an initial assay. A method for testing four different cell densities and four different FCCP concentrations using two cell culture plates, two cartridges and the XF Cell Energy Phenotype Test Kit with an instrument is recommended for initial assays. A method for testing four different cell densities using an XF24 Cell Culture Microplate, XFe24 sensor cartridge and the Seahorse XF Real-Time ATP rate assay kit with an instrument is recommended for initial assays. A method for testing 2-4 different cell densities using an XFp Cell Culture Miniplate, XFp cartridge and the Seahorse XF Real-Time ATP rate assay kit with an XFp instrument are recommended for initial assays.

This is a suggested XF96 assay plate map for seeding four cell densities:

Seeding for Cell Density Titration Assay

This is a suggested assay plate map for seeding four cell densities:

Seeding for FCCP Concentration Titration Assay

If you have already performed the cell seeding density assay and/or know the optimal number of cells per well, the FCCP titration assay may be performed using the optimal cell number (1.0 X cells/well) seeded in all wells except Background Correction wells. Otherwise, follow the same instructions for cell seeding and cartridge hydration/preparation as shown below, and use the following suggested plate layout for testing four concentrations of FCCP:

There are two workflow options: (1) For cells that are NOT limited in number, multiple XFp cell culture miniplates can be seeded at different densities to reduce the time between experiments and complete the characterization workflow more quickly (Accelerated Workflow). (2) For cells limited in number, additional cells are prepared after the results of the first experiment are determined (Standard Workflow).

Experiment	Rationale	Accelerated Workflow	Standard Workflow
Seed cells at single or different densities and visually assess degree of cell confluence; choose a miniplate for the next step.	To generate metabolic rates within the dynamic range of the instrument, cells should be 50-90% confluent. Visual assessment is a good first approxima- tion of optimal cell density and will be verified in each assay.	Seed 1-2 miniplates at 2-4 different densities according to the diagram below.	Seed 1 miniplate at a single cell density; hydrate 1 XFp cartridge.

Basic procedures for seeding adherent cells (typically performed the day before the XF assay)

Choose 2-4 cell densities to test, based on standard or accelerated workflow described above. Either cover the range found in the references above, or seed the recommended cells/well value (1X) plus 0.5X, 2X and 4X cells per well.
Remove a three-pack of miniplates from the blue box.
Remove the foil seal from the tub(s) that will be used.
Add sterile water or PBS to the moat around the cell culture wells. Use an 8-channel pipettor set to 200 μL, and fill both sides of the moat (two tips will fit into each chamber). If no multi-channel pipette is available, fill each chamber of the moat with 400 μL of sterile water or PBS (total 3200 μL).
Add 80 μL of growth medium only (no cells) to wells A and H. These are background correction wells.
A two-step seeding process is recommended when seeding Agilent Seahorse XF24 Cell Culture Microplates. The two-step process produces a consistent and even monolayer of cells.
Harvest and re-suspend the cells to desired final concentration to seed in 80 μL of growth medium. Optimal cell seeding numbers vary widely, though are typically between 5×10³ – 4×10⁴ cells per well and must be determined empirically. (For example, for 1 x 10⁴ cells per well, resuspend cells 1 x 10⁴ per 80 μL = 1.25 x 10⁵ cells per mL)
Harvest and re-suspend the cells to desired final concentration to seed in 100 μL of growth medium. Optimal cell seeding numbers vary widely, though are typically between 1×10⁴ – 8×10⁴ cells per well and must be determined empirically. (For example, for 2 x 10⁴ cells per well, resuspend cells 2 x 10⁴ per 100 μL = 2.0 x 10⁵ cells per mL)
Seed 80 μL of cell suspension per well; do not seed cells in background correction wells (A1, A12, H1, H12). Be sure to put medium only (no cells) in the background correction wells.
Seed 100 μL of cell suspension per well; do not seed cells in background correction wells (A1, B4, C3, D6). Be sure to put medium only (no cells) in the background correction wells.
Seed 80 μL of cell suspension per well in wells B - G, do not seed cells in background correction wells (A and H). Be sure to put medium only (no cells) in the background correction wells.
IMPORTANT: Allow plate to rest at room temperature in the tissue culture hood for one hour.¹ This can promote even cell distribution and reduce edge effects for some cell types. Monitor adherence using a microscope.
Place the plate in a standard cell culture incubator to allow cells to adhere. This generally takes approximately 1 hour for strongly adherent cells, but may take 5-6 hours for less adherent cell types. Monitor adherence using a microscope.
After the one hour rest step, check cells for adherence.
If cells are well-adhered, dispense an additional 150 μL of cell growth media to each well (250 µL total), then transfer plate to a standard cell culture incubator.
If cells are not well-adhered to the plate, allow an additional 1-5 hours for the cells to firmly attach (in the biosafety cabinet), then add an additional 150 µL of growth media to each well (250 µL total) and transfer plate to a standard cell culture incubator.
After cells have adhered, add 150 μl of growth medium to each well, bringing the total volume of medium in the well to 250 μl. When adding medium to the wells, add it slowly to the sides as not to disturb the newly attached cells.
Allow the cells to grow overnight in a cell culture incubator. Monitor growth and health of cells using a microscope.

Prepare Cell-Tak coated Cell Culture plate(s) Miniplate(s) as described below:

The optimal Cell-Tak solution concentration for Agilent Seahorse Cell Culture Microplate Miniplate is 22.4 μg/mL.
Prepare 2.5 mL 1.5 mL 0.25 mL of this solution per plate for each assay. Refer to the Manufacturer's protocol to prepare this solution.
Apply 25 50 μL of the solution to each well for 20 minutes at room temperature.
Wash each well twice using 200 μL of sterile water.
Cell-Tak-coated Seahorse Cell Culture Microplates Miniplates may be stored for up to 1 week at 4°C.
Cell-Tak coated Cell Culture Microplates Miniplates Cell Culture Microplates must be allowed to warm to room temperature in the hood before cell seeding.

Hydrate Cartridge

Basic procedures for hydrating the cartridge

An important component of the XFp assay platform is the sensor cartridge. Each probe tip of the sensor cartridge is spotted with a solid-state sensor material that detects changes in both pH and O₂ concentration over time to calculate rates. In order for the sensors to function correctly, they must be thoroughly hydrated.

The Day Prior to the XFp assay:

Aliquot at least 20 mL of XF Calibrant into a 50 mL conical tube. Place this in a non-CO₂ 37° C incubator overnight.
Aliquot at least 5 mL of XF Calibrant into a 15 mL conical tube. Place this in a non-CO₂ 37° C incubator overnight.
Open the Extracellular Flux Assay Kit, and remove the contents.
Obtain a three-pack of cartridges from the green box. Remove the foil seal from the tub(s) that will be used.
Place the sensor cartridge upside down next to the utility plate.
Separate the utility plate and Sensor Cartridge, and place the sensor cartridge upside down next to the utility plate.
Fill each well of the utility plate with 200 μL of sterile, tissue culture grade water.
Fill the moats around the outside of the wells with 400 μL per chamber.
Lower the sensor cartridge onto the utility plate, submerging the sensors in the water.
Verify the water level is high enough to keep the sensors submerged.
Place in a non-CO₂ 37° C incubator overnight. To prevent evaporation of the water, verify that the incubator is properly humidified.

Open the Agilent Seahorse Flux Assay Kit and remove the contents.
Place the Sensor Cartridge upside down next to the Utility Plate.
Fill each well of the Utility Plate with 1 mL of XF Calibrant.
Place the Hydro Booster on top of the Utility Plate.
Lower the Sensor Cartridge through the openings on the Hydro Booster plate, into the Utility Plate submerging the sensors in XF Calibrant.
Verify the XF Calibrant level is high enough to keep the sensors submerged.
Place in a non-CO₂ 37°C incubator overnight. To prevent evaporation of the XF Calibrant, the incubator should be humidified.
IMPORTANT NOTE: The Hydro Booster must be removed prior to placing the Sensor Cartridge into the Agilent Seahorse Analyzer. Failure to do so may result in damage to both the Sensor Cartridge and the Analyzer. See Section 3 for further instructions.

Design Experiment

Wave Desktop software is used for designing XF assays for the Seahorse XFe and XFp Analyzers. Use the resources below to learn more about using Wave Desktop software for assay design, including the elements of an assay template, modifying instrument protocol for custom assays, managing template files, and using the prepopulated catalog.

Wave Desktop software allows you to easily create & customize assay template files to run on the Seahorse Analyzer.

What is an assay template file? Think of assay template files as an electronic copy of the experiment you designed in your lab notebook. The information entered in your assay template file is stored as a record of your experiment within the result file, which can be shared & re-run by you or other collaborators, provides structure & organization to your result data after assay completion, and offers valuable troubleshooting info when needed.

The 3 elements of an assay template file are:

Group Definitions
Plate Map
Instrument Protocol

Group Definitions

Open Wave 2.6 software
Click Templates (located below Wave Home)
Open the assay template called XF Real-Time ATP Rate Assay
On the Group Definitions view, you will see prepopulated information for the injection strategy, pretreatments, assay media and cell type.
Double-click Pretreatments and delete the Control & Experimental entries.
Double-click Cell Type and delete the default entry called Cells (See Cell Reference Database).
Within the Cell Type group definition, click Cell Type and Add to add a new cell type entry and enter the name of cell type you intend to analyze in your assay. It is recommended to add the seeding density to group name. For example, the C2C12 Cell Type with a seeding density of 20,000 cells per well would be named: 20k C2C12
Repeat 3 times for each Cell Type definition.

Note: Due to the XFe24 Analyzer's 24-well microplate format, this cell seeding density optimization protocol can be performed using 1 cell plate with 4 cell seeding densities (n=5 per group).

Note: Due to the XFe96 Analyzer’s 96-well microplate format, this cell seeding density optimization protocol can be performed using 1 cell plate with 4 cell seeding densities (n=22-24 per group).
Note: Due to the XFp Analyzer’s 8-well miniplate format, this cell seeding density optimization protocol must be performed using two cell plates with 2 cell seeding densities per plate (n=3 per group). When designing your assay template, you can:
- Create a new assay template for the 3rd and 4th cell seeding density groups.
- Add 4 cell seeding density groups to one assay template and reassign the 3rd and 4th cell group to the plate map after performing the first assay with cell seeding density groups 1 and 2.
- Rename groups in this template after performing the first assay with cell seeding density groups 1 and 2.

Generate Groups

The next step is to assign groups to the plate map.

Plate Map

Click Plate Map in the functions ribbon (under "Assay Navigation").
Assign the first cell seeding density group to the plate map. To assign a group to the plate map, first click the group name in the group list, then:
- Click the column header (i.e. 1, 2, 3, etc.) or the row header (i.e. A, B, C, etc.)
- Drag & drop an area of wells on the plate map using your mouse left-click.
- Click individual wells on the plate map (not recommended for this assay template).
Repeat for the next cell seeding density group. The suggested plate map layout is pictured above/below.

Instrument Protocol

Click Instrument Protocol in the functions ribbon (under “Assay Navigation”) to view or edit the instrument protocol.
Note: The default instrument protocol is does not require modifications, however you can change the name of a protocol command, the number of measurements before/after an injection, or the length of time each measurement is performed.
- Modifying the instrument protocol settings directly affects how data is acquired during your assay. For this example, the default instrument protocol is used (and recommended).
- Should you need to modify the default instrument protocol, prior to performing your cell seeding density optimization assay it is recommended to review the instrument protocol section in the Wave User Guide, or if necessary, contact Agilent Cell Analysis Technical Support.
Last, click Run Assay in the functions ribbon (under "Assay Navigation") to add additional experimental details, save the template file, and start the cell seeding density optimization assay.

Click Run Assay in the functions ribbon (under "Assay Navigation") to add additional experimental details and save the template file.

Wash Cells

Basic procedure for washing adherent cells

For adherent cells seeded at least one day prior to the XFp assay:

Retrieve the cell culture miniplate from the CO₂ incubator.
View the cells under the microscope to:

Confirm cell health, morphology, seeding uniformity and purity (no contamination).
Ensure cells are adhered, with a consistent monolayer.
Make sure there are no cells in the background correction wells.

Wash adherent cells with complete assay medium: one time with XF Real-Time ATP Rate Assay Media:

Remove all but 20 μL of the culture medium from each well. The small amount of medium is left to keep the cells from drying out.
Gently add 200 μL of assay medium.
Place the plate in a 37°C incubator without CO₂ for one hour prior to the assay.

Just prior to starting the assay, wash the cells again with XF Real-Time ATP Rate Assay Media: remove all media but 20 μL and add fresh media to a final volume 180 μL. Inspect the cells under the microscope to ensure that cells were not disturbed or washed away.

Remove all but 50 μL of the culture medium from each well. The small amount of medium is left to keep the cells from drying out.
Gently add 1mL of assay medium, then remove the same amount.
Repeat step b, removing all but 50 μL (as in step a).
Add 450 μL assay medium (to a total volume of 500 μL) for a 24 well platform instrument.

Remove all but 50 μL of the culture medium from each well. The small amount of medium is left to keep the cells from drying out.
Gently add 1mL of assay medium.
Place the plate in a 37°C incubator without CO₂ for one hour prior to the assay.
Just prior to starting the assay, wash the cells again with XF Real-Time ATP Rate Assay Media: remove all media but 50 μL and add fresh media to a final volume 500 μL. Inspect the cells under the microscope to ensure that cells were not disturbed or washed away.

Observe the assay wells under the microscope to ensure that cells were not washed away.
Place the plate in a 37° C incubator without CO₂ for one hour prior to the assay.

Basic procedures for seeding suspension cells

For one Seahorse Cell Culture Microplate, transfer an appropriate volume of cell suspension from the growth vessel to a conical tube.
To calculate the total number of cells needed, multiply the desired number of cells per well times 100 wells for the Seahorse XFe96. (For example, 150,000 cells per well × 100 wells = 1.5 × 10⁷ cells).
To calculate the total number of cells needed, multiply the desired number of cells per well times 10 wells for the Seahorse XFp. (For example, 150,000 cells per well × 10 wells = 1.5 × 10⁶ cells).
Centrifuge cells at room temperature at 200 × g for 5 minutes.
While cells are being centrifuged, pipette 50 μL assay medium into background/control wells of the room-temperature Cell-Tak-coated Seahorse XF96 Cell Culture Plate.
While cells are being centrifuged, pipette 50 μL assay medium into background/correction wells (A and H) of the room-temperature Cell-Tak-coated Seahorse XFp Cell Culture Plate.
Remove supernatant from the centrifuged conical tube.
Resuspend cells in warmed assay medium to the desired concentration of cells per well in 50 μL of assay medium. (For example, 1.5 × 10⁵ cells per well is desired, resuspend cells in a volume that results in 1.5 × 10⁵ cell/50 μL or 3.0 × 10⁶ cells/mL).
Change centrifuge settings to zero braking.
Transfer the cell suspension to a sterile tissue culture reservoir, or pipette from the conical tube.
Pipette 50 μL of the cell suspension along the side of each well, except for background/control wells. It is recommended to use a multichannel pipette.
Place the miniplate(s) in an XFp carrier tray and centrifuge at 300 x g for 1 min with no brake. The carriers are designed to hold up to 3 miniplates, and fit standard centrifuge microplate adapters. Ensure that the centrifuge rotor is balanced appropriately.
After centrifugation, visually confirm adherence of the cells to the well bottom.
Centrifuge the cells at 200 × g (zero braking) for 1 minute. Ensure that the centrifuge is properly balanced.
Taking care not to disturb the cells on the bottom, gently add 130 μL assay medium to each well to the desired initial assay volume (for 180 μL starting assay volume).
Add sterile water or PBS to the moat around the cell culture wells, 100 μL per chamber. Using an 8-channel pipettor (if available) set to 50 μL, fill both sides of the moat using two tips per chamber. If no multi-channel pipette is available, individually fill each chamber of the moat with 100 μL of sterile water or PBS (total 800 μL).
Transfer plates to a 37° C incubator not supplemented with CO₂ for 25–30 minutes to ensure that the cells have completely attached. Visually confirm that most of the cells are stably adhered to the culture surface.
Slowly and gently, add 130 μL warm assay medium along the side of each well. Take care to avoid disturbing the cells.
Observe the cells under the microscope to check that cells are not detached.
Return the cell plate to the incubator for 15–25 minutes.
After 15–25 minutes, the cell plates are ready for your assay. Total time following centrifugation should be no greater than 1 hour for best results.

For one Seahorse XF24 Cell Culture Microplate, transfer an appropriate volume of cell suspension from the growth vessel to a conical tube.
To calculate the total number of cells needed, multiply the desired number of cells per well times 25 wells for the Seahorse XF24. (For example, 150,000 cells per well × 25 wells = 3.75 × 10⁶ cells).
Centrifuge cells at room temperature at 200 × g for 5 minutes.
While cells are being centrifuged, pipette 100 μL assay medium into background/control wells of the room-temperature Cell-Tak-coated Seahorse XF24 Cell Culture Plate.
Remove supernatant from the centrifuged conical tube.
Resuspend cells in warmed assay medium to the desired concentration of cells per well in 100 uL of assay medium. (For example, 1.5 × 10⁵ cells per well is desired, resuspend cells in a volume that results in 1.5 × 10⁵ cell/100 μL or 1.5 × 10⁶ cells/mL).
Change centrifuge settings to zero braking.
Transfer the cell suspension to a sterile tissue culture reservoir, or pipette from the conical tube.
Pipette 100 μL of the cell suspension along the side of each well, except for background/control wells. Agilent recommends using a multichannel pipette.
Centrifuge the cells at 200 × g (zero braking) for 1 minute. Ensure that the centrifuge is properly balanced. For XFp Analyzer users, Agilent recommends using the Agilent Seahorse XFp Carrier Tray to centrifuge the Seahorse XFp Cell Culture Miniplates. For more details, refer to the Basic Procedure: Seeding Suspension Cells in XFp Cell Culture Miniplates.
Transfer plates to a 37° C incubator not supplemented with CO₂ for 25–30 minutes to ensure that the cells have completely attached. Visually confirm that most of the cells are stably adhered to the culture surface.
Slowly and gently, add 400 μL warm assay medium along the side of each well. Take care to avoid disturbing the cells.
Observe the cells under the microscope to check that cells are not detached.
Return the cell plate to the incubator for 15–25 minutes.
After 15–25 minutes, the cell plates are ready for your assay. Total time following centrifugation should be no greater than 1 hour for best results.

Types of Data

Cellular oxygen consumption (respiration) and proton excretion (glycolysis) cause rapid, easily measurable changes to the concentrations of dissolved oxygen and free protons. Agilent Seahorse XF Analyzers measure concentrations of dissolved oxygen and free protons in real-time by isolating an extremely small volume (about 2 μL) of medium above a monolayer of cells within a microplate then calculate the OCR and ECAR, respectively.

Using Wave Desktop software, you can easily access & review these data:

Rate Data is the primary output of the XF analyzer.

Oxygen Consumption Rate (OCR): A quantitative measurement of oxygen consumption in the well, an indicator of mitochondrial respiration, reported in picomole/minute (pmol/min) vs. time.
Oxygen Consumption Rate (OCR) data displayed in Rate mode (right).
Extracellular Acidification Rate (ECAR): A qualitative measurement of proton extrusion in the extracellular medium, reported as milli-pH/minute (mpH/min) vs. time.
Extracellular Acidification Rate (ECAR) data displayed in Rate mode (right)
Proton Efflux Rate (PER): A quantitative measure of extracellular acidification that accounts for media buffering capacity and plate geometry. Reported in picomole/minute (pmol/min) vs. time. Only available in post-run assay results, not during assay runtime.

See chapter 3 in the Wave User Guide for more information about the types of data available in Wave software.

Level Data is used to calculate rate data and can also be used for diagnostic purposes.

Oxygen Concentration (mmHg): As cells (or other biological material) consumes oxygen during a measurement, oxygen tension will decrease. This decrease in oxygen tension is used to calculate the rate of oxygen consumption (OCR). You can view oxygen tension level data on the Overview analysis view using the Y1 drop-down menu.
Oxygen tension (O₂) data displayed as mmHg vs. time in Level mode (right)
Proton Concentration (mpH): As cells (or other biological material) generate protons during a measurement, proton concentration will increase. The concentration of free protons in the microchamber is measured throughout an XF assay and calculated as the rate of extracellular acidification (ECAR). You can view mpH level data on the Overview analysis view using the Y1 drop-down menu.

Data Display Options

Wave provides a standard set of graphing options to view & interpret assay result data. Depending on the type of analysis view selected, Wave automatically calculates and graphs result data as one of the following:

Kinetic Graph

A Kinetic Graph is the most common way to display rate data from XF Analyzers. A kinetic graph displays the rate on the y-axis, and time on the x-axis. During an assay, data is acquired and plotted in real-time as a kinetic graph. Kinetic graphs can be found in the Quick View and Overview analysis views in Wave software.

Energy Map

Another common way to graph XF result data is an Energy Map (scatter plot), where Oxygen Consumption Rate (OCR) is always plotted on the y-axis, and acidification data (ECAR or PER) is always plotted on the x-axis. Use the Measurement drop-down menu to select a rate measurement to display on the energy map for each group. Use the Rate drop-down menu to change the x-axis rate to PER. The energy map graph option can be found in the Quick View and OCR vs. ECAR analysis views.

Plate Map

The Plate Map displays rate data for the selected rate measurement of each assay well. Plate Maps are always displayed in the upper right corner of Wave while running an assay, and on the Quick View, Overview, and OCR vs. ECAR analysis views. The Quick View has a button to display the Plate Map, which is hidden by default.

The Plate Map in the Quick View and OCR vs. ECAR analysis views displays two rates: Oxygen Consumption Rate (OCR - top) and acidification data (either ECAR or PER - bottom). The Plate Map on the Overview analysis view displays 1 rate - OCR, ECAR, or PER.

When opening a new analysis view, the Plate Map shows data for rate measurement 1 by default. Use the Rate drop-down menu to display data for another rate measurement during the assay.

Bar Graph

The Bar Graph is available on the Overview analysis view only (below the Plate Map), and displays the average rate for each group for the selected measurement. Use the Display drop-down menu to change the rate display from Group (average) to Well (individual well) mode.

The Bar Graph can be used for identifying outliers, optimal FCCP concentration, optimal cell seeding density, or other trends that may not be apparent when measurement data is plotted as a kinetic graph or scatter plot.

Group List

The Group List is the legend for the data plotted in the kinetic graph or scatter plot.

Use the Group List to:

Hide or show groups from the graphed data by double-clicking the group name.
Check the Details box in the upper-right corner of the Group List to display group statistics. Statistics are displayed as average and error for the selected rate measurement. Select a different rate measurement to display group statistics for that rate.
Assay wells that have been turned OFF on the Plate Map are not included in the calculated group statistics.
When a group is hidden, the mean and standard deviation of the group will be: Mean: 0.00; Standard Deviation: 0:00.

See chapter 3 in the Wave User Guide for more information about the types of data available in Wave software.

Analysis Views

There are 4 customizable analysis views that can be added to an assay result file in Wave Desktop. Each analysis view can be added to an assay result file multiple times using the Add View button in the top-level ribbon menu.

Quick View

Quick View is the default analysis view displayed when opening a new assay result file. Quick View simultaneously displays a kinetic graph of OCR vs time, ECAR vs time, and an energy map of OCR vs. ECAR.

Overview

Overview displays a kinetic graph of rate (OCR, ECAR, PER, or PPR) versus time. The selected rate is displayed on the y-axis, and time is displayed on the x-axis. Group statistics (average rate and error) for each measurement can be displayed by checking the Details box in the Group List below the kinetic graph. Overview is the most versatile analysis view in Wave software for routine analysis functions. To display Overview, click Add View and select Overview from the list of views.

Tip: Add multiple Overview analysis views by repeating the process of Add View > Overview. This gives greater flexibility for tailoring your result data presentation to show specific groups, responses, or comparisons between groups.

OCR vs. ECAR

The OCR vs. ECAR view displays an energy map with the OCR on the y-axis and (by default) ECAR on the x-axis. Use the Rate drop-down menu to change the rate displayed on the x-axis to either PER or PPR. OCR is always displayed on the y-axis, and cannot be changed. To display OCR vs. ECAR, click Add View and select OCR vs. ECAR from the list of views.

Data

The Data view contains all data associated with the assay result file organized into 7 tabs:

Group Data: Average rate data (OCR, ECAR, PER, or PPR) and error for each group, ordered by measurement number.
Rate: Individual well rate data (OCR, ECAR, PER or PPR) ordered by measurement number. Error values are not displayed.
Level Data: Individual well level data (O₂ and pH) ordered by measurement number.
Raw: Raw measurement data, including O₂ and pH light emission values, reference values, well and environment temperature recorded each measurement. This tab is most-commonly used by Tech Support, not for routine data analysis.
Calibration: O₂ and pH calibration results organized by well.
Calibration View: O₂ and pH calibration results for each assay well displayed as a plate map.
Event Log: Assay information such as analyzer serial number, software version, plate & barcode lot numbers, and other settings during the assay. Also provided is a sortable table of protocol commands used during the XF assay, including command name, timing, and outcome.

To display the Data view, click Add View and select Data from the list of views. The Group Data tab is displayed by default when opening the Data view.

See Chapter 3 in the Wave User Guide for more detailed information about each analysis view, including recalculating data as a % of baseline, normalize rate data to a biological parameter (i.e. cell number), flag assay wells on the plate map, and other key analysis functions & features.
