Bradford dye assay
WebThe Bradford assay is a colorimetric assay that relies on the binding of the dye Coomassie Brilliant Blue G-250 to proteins, resulting in a shift in the absorbance maximum of the dye from 465 nm to 595 nm. The intensity of the color change is directly proportional to the concentration of protein in the sample. WebSome common substances that potentially interfere with protein assay methods are reducing agents (e.i. DTT) and detergents (i.e. Triton X-100). In general, samples containing reducing agents or copper-chelating agents are preferentially analyzed with Coomassie dye–based assays (Bradford method).
