Bradford assay wikipedia

WebThe Bradford protein assay is a time-tested colorimetric assay. When the Bradford reagent (acidified Coomassie Brilliant Blue G-250) binds to proteins, the dye undergoes a color change in the visible spectrum, with the absorbance maximum moving from 470 to 595 nm. The absorbance at 595 nm is then read either in a spectrophotometer or a ... WebPrinciple. The Bradford assay, a colorimetric protein assay, is based on an absorbance shift of the dye Coomassie Brilliant Blue G-250 in which under acidic conditions the red form of the dye is converted into its bluer form to bind to the protein being assayed. During the formation of this complex, two types of bond interaction take place: the ...
