Bradford protein assay principle

WebThe Bradford protein assay is used to measure the concentration of total protein in a sample. The principle of this assay is that the binding of protein molecules to Coomassie dye under acidic conditions results in a color change from brown to blue. Who created the Bradford assay? Marion M. Bradford WebThe Bradford Protein Assay is a quick, inexpensive and simple way to determine protein concentration. A protein is reacted with the Bradford reagent and absorbance is measured. ... quantities of protein utilizing the principle of protein-dye binding. Analytical Biochemistry, 72(1), 248-254.
