WebThe Quick Start™ Bradford protein assay is a simple and accurate procedure for determining the concentration of protein in solution. The assay supplies ready-to-use dye reagent at 1x concentration and two … WebThe Bradford assay is based on the binding of protein to a dye, leading to a shift in the absorbance maximum of the dye. After creating a standard curve of protein solutions with known concentrations, the protein concentration of unknown samples can be calculated. The dye used for the Bradford assay is Coomassie ® Brilliant Blue G-250 (Figure 1).
WebThe dye is kept at a low pH (green color) and the mixture of Bradford solution looks brown. The formation of protein/dye complex will stabilize the negatively charged anionic form of the dye making a blue color. *The dye binds to exposed surfaces of basic and aromatic AAs.
