WebThe Bradford assay is based on the binding of protein to a dye, leading to a shift in the absorbance maximum of the dye. After creating a standard curve of protein solutions with known concentrations, the protein concentration of unknown samples can be calculated. The dye used for the Bradford assay is Coomassie ® Brilliant Blue G-250 (Figure 1). WebTo perform the Bradford assay, a series of protein standards with known concentrations are prepared in a range spanning the expected concentration of the sample being tested. …
