Quantification of Total Protein Using Bradford Protein Assay Pre-Lab Your pre-lab assignment is to plan how you will prepare your BSA standard solutions for the calibration curve. A 2 mg/mL BSA stock solution will be available. You can simply dilute with deionized water. You will need to make 25 microliters of each of the following concentrations. For the first concentration, you will need to make 160 microliters so that the BSA volume is large enough that it can be measured...
