Prepare a standard curve from the data below from a Bradford assay. Samples were prepared from a 0.100 mg/mL egg white lysozyme stock solution in a 100.0 mM, pH 7.0 phosphate buffer at various dilutions in a final volume of 1.0 mL. The data is shown in the table below: Dilution (%) 0.0 (blank) 2.5 → 0.0025 mg 5.0 → 0.005 mg Absorbance @ 595 nm (1 cm pathlength) 0.000 0.031 0.075 10.0 → 0.01 mg 0.134 15.0 → 0.015 0.229 20.0 → 0.02 0.280 25.0 → 0.025 0.386 37.5 → 0.0375 0.540 50.0 → 0.05 mg 0.742
