The Bradford Protein Assay is the preferred colorimetric assay for quantifying total protein concentration. Based upon complex formation between basic and aromatic amino acid residues with Coomassie® Brilliant Blue G-250 dye, the Bradford method is easier, faster, and more sensitive than the Lowry method. The standard protocol is used for measuring 10-100 μg of protein and the microassay is used for measuring 1-10 μg of protein. For maximum convenience, Bradford Reagent and 0.5 mg/ml BSA standard solution are offered individually or as components of a kit.

Pierce BCA™ (bicinchoninic acid) reagents provide accurate determination of protein concentration with most sample types encountered in protein research. The Pierce BCA™ Protein Assay can be used to assess yields in whole cell lysates and affinity-column fractions, 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 protein-to-protein uniformity.
