The gateway to thousands of research services and custom products. When the Coomassie dye binds to protein in an acidic medium, an immediate shift in absorption maximum occurs from 465 nm to 595 nm with a concomitant color change of the solution from brown to blue. Can I ask customer to use ab102535 or ab119216 against the below queries ? When mixed with a protein solution, the acidic Coomassie-dye reagent changes color from brown to blue in proportion to the amount of protein present in the sample. Bradford Protein Assay Kit (B-Pak) is a straightforward and rapid kit for determining the concentration of proteins in solution. General description Bradford assay is addition of coomassie brilliant blue G-250 to protein solution.
