Protein Assays
Protein assay kits, reagents and standards to determine total protein concentration of samples containing different buffer components; protein quantitation is often necessary for isolation, separation, and analysis of proteins by biochemical methods.
Our protein assay reagents and kits include convenient and reliable formulations of industry-standard BCA and Bradford assay reagents for determining protein concentration. We invented the wildly popular BCA protein assay, but we've never stopped advancing methods to improve and extend the accuracy, flexibility and convenience of this and other assay techniques. Trust the recommendation of thousands of research paper citations, choose one of our Pierce* Protein Assay Kits, and rely on our expert technical support scientists to help with any challenges you encounter.

Class-Specific Protein Assay Kits
Specialized protein assay reagents and kits to estimate and measure specific post-translational modification (PTM) or functional (enzymatic) classes of proteins in biological samples, including glycoproteins, phosphoproteins and proteases.
Total Protein Assay Kits
Bradford assay reagents, BCA assay kits, albumin (BSA) standards and other spectrophotometer and microplate protein assay methods to accurately quantify, determine and measure total protein concentration following cell lysis, labeling or purification.
Target-Specific Protein Assay Kits
Microplate and pull-down kits designed to capture, detect and measure specific proteins and biological sample components by a variety of probe methods (e.g., antibody, dye, substrate, receptor).
