he Pierce BCA Protein Assay Kit is a high-precision, detergent-compatible protein assay for determination of protein concentration. Pierce BCA reagents provide accurate determination of protein concentration with most sample types encountered in protein research. The Pierce BCA assay can be used to assess yields in whole cell lysates, affinity-column fractions, purified proteins samples, as well as to monitor protein contamination in industrial applications. Compared to most dye-binding methods, the BCA assay is affected much less by protein compositional differences, providing greater concentration accuracy.
