Product Information: Protein Quantitation Kit: Simple and Rapid Kit for Determining Protein concentration in solution. 1000 Assays. Background: The Protein Quantification Kit provides a simple and rapid procedure for determining the concentration of protein in solution. The method utilizes an improved Coomassie blue G reagent which forms a blue complex in the presence of protein. The intensity of the blue complex is proportional to the amount of protein in the sample and can be easily measured b
