Major interferences in bradford protein assay
WebThe Bradford protein assay is based on the observation that the absorbance maximum for an acidic solution of Coomassie Brilliant Blue G-250 shifts from 465 to 595 nm when binding to protein occurs. The extinction coefficient of a dye-albumin complex solution is constant over a 10-fold concentration range. Thus Beer's law may be applied for ... Web1 apr. 2024 · The Bradford assay is a quick and fairly sensitive method for measuring the concentrations of proteins.
