Bradford Protein Assay Reagent is a fast protein quantification method. It’s based on the method of Bradford, Coomassie-binding with protein in an acidic solution. The measurement of absorbance shifts from 645nm (brown color) to 595nm (blue color) when binding to protein occurs. In addition, the coloration differs greatly depending on the basic and aromatic amino acid residues of protein. Bradford Protein Assay Reagent provides a wide protein quantification range from 1-1,000 µg/mL and the measured absorbance at 595nm is stable for 5 to 60 minutes after the binding reaction starts.
