The Bradford protein assay (also known as the Coomassie protein assay) was developed by Marion M. Bradford in 1976. [1] It is a quick and accurate [2] spectroscopic analytical procedure used to measure the concentration of protein in a solution. The reaction is dependent on the amino acid composition of the measured proteins.
Marion Mckinley Bradford (October 28, 1946 - May 3, 2021) was an American scientist [1] who developed and patented the Bradford protein assay, [2] a method to quickly quantify the amount of protein in a sample. [3] [4] His paper describing the method is among the most cited scholarly articles of all time. [5] [6] [7]
The Bradford assay uses the spectral properties of Coomassie brilliant blue G-250 to estimate the amount of protein in a solution. [19] A protein sample is added to a solution of the dye in phosphoric acid and ethanol. Under the acid conditions the dye is normally a brownish colour but on binding to the protein the blue form of the dye is produced.
Bradford assay method uses a dye to bind to protein. Most commonly, Coomassie brilliant blue G-250 dye is used. When free of protein, the dye is red but once bound to protein it turns blue. [11] The dye-protein complex absorbs light maximally at the wavelength 595 nanometers and is sensitive for samples containing anywhere from 1 ug to 60 ug.
The Bradford assay is a molecular biology technique which enables the fast, accurate quantitation of protein molecules utilizing the unique properties of a dye called Coomassie Brilliant Blue G-250. [41] Coomassie Blue undergoes a visible color shift from reddish-brown to bright blue upon binding to protein. [41]
