Bradford assay was used to determine bovine serum albumin (BSA) concentrations. The method works by binding Coomassie Brilliant Blue dye to protein standards and unknown, leading to a shift in the absorbance maximum of the dye. A stock solution of BSA is available (10 mg/ml) from which the protein standards were prepared. Bradford reagent, 290 ul, was pipetted into a transparent 96-well microplate. 10 ul of the protein dilution was added followed by mixing in the wells. After 5 min of incubation at room temperature, the plate was read in spectrum mode with the absorbance spectrometer of the microplate reader. The spectrum of the dye not bound to protein was also determined. Create a standard curve or regression equation that related the protein concentration and absorbance. An unknown BSA sample was prepared the same way as the standard and the OD was 0.35. determine the original concentration of the protein solution. The measurements can be seen below. 0.0625 Protein Concentration…
