Protein quantification using bradford assay
WebbThe 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. WebbAbstract. A rapid and accurate method for the estimation of protein concentration is essential in many fields of protein study. An assay originally described by Bradford ( 1) …
