Many protein-containing solutions have the highest absorption at 280 nm in the spectrophotometer, the UV range. This requires spectrophotometers capable of measuring in the UV range, which many cannot. Additionally, the absorption maxima at 280 nm requires that proteins contain aromatic amino acids such as tyrosine (Y), phenylalanine (F) and/or tryptophan (W). Not all proteins contain these amino acids, a fact which will skew the concentration measur… WebThe Standard curve of Bradford Assay Y=0,0053x + 0,0065 x = (y-0,0065)/0,0053 x = (0,7597-0,0065)/0,0053 X= 142,1132 mg/ml 3 3.0 Discussion [10 marks] The Bradford protein assay uses a dye, Coomassie Brilliant Blue G-250, which was first reported by Dr. Marion Bradford in 1976.
