Agilent Technologies publishes new method for improved protein characterization

Company offers 15 percent discount on purchase of combined products

PALO ALTO, Calif., April 2, 2003


Agilent Technologies Inc. (NYSE: A) today announced a method for improved protein characterization stemming from synergies between their lab-on-a-chip and high performance liquid chromatography (HPLC) products. To promote the value of combining these products for protein analysis, Agilent is offering a 15 percent discount to customers purchasing an Agilent 2100 bioanalyzer combined with a Protein LabChip® kit of choice and Agilent 1100 Series LC system (including pump, autosampler and detector) between April 1 to Sept. 30, 2003.

In the newly published method, reversed-phase (RP) HPLC is used to separate proteins by hydrophobicity, while the 2100 bioanalyzer -- together with the Protein 200 Plus LabChip -- efficiently analyzes the sample based on protein size. The use of these orthogonal methods together distinguishes contaminants that would otherwise have remained unidentified, improving the quality and reliability of purification and protein identification.

Both the Agilent 2100 bioanalyzer and the Agilent 1100 Series HPLC are market-leading instruments commonly used for protein analysis, purification and characterization. Since its introduction three years ago, the Agilent 2100 bioanalyzer and LabChip kits, co-developed with Caliper Technologies, have been established as the market-leading microfluidics-based system for analyzing RNA, DNA, proteins and cell fluorescence. In this application, the 2100 bioanalyzer not only determines protein masses faster and easier than conventional SDS-PAGE, but also serves as a complementary analytical method to RP-HPLC.

The Agilent 1100 Series is an industry-leading HPLC system and covers a flow range from nanoliters to 100 ml/min. The system is an extremely precise and reliable tool for separating proteins and peptides by means of RP, ion exchange or size-exclusion chromatography.
