You used the Bradford assay in lab to generate the standard curve below using standard protein solutions. A sample containing protein was diluted 50 fold and the corresponding absorbance was measured at 0.30. What is the protein concentration of the sample? The equation of the line is y-0.0023x. 0 7 0.6 0.5 04 0.3 0.2 0 1 0 0 50 100 150 200 250 300 Protein Concentration (mg/mL) 0.625 mg/mL 0.68 mg/mL O130 mg/mL 6522 mg/mL
