Protein Analysis Kits - Details & Specifications

The Agilent Protein 230 and Protein 80 kits provide a fast and easy way to analyze a wide range of samples from the analysis of recombinant protein expression, to optimization of protein purification, and protein validation and QC.

Analysis of an IgG2 antibody preparation under reducing conditions with the 2100 Bioanalyzer system and the Protein 80 and Protein 230 assays. The light chains (LC) and the heavy chains (HV) are well resolved. Aggregates of higher molecular weight and low molecular weight impurities are observed. Under non-reducing conditions the intact antibody as well as a mixture of LC and HC and the non-glycosylated form of IgG2 is detected. (Application Note 5990-5283EN)
