You have a solution of bovine serum albumin at 3mg/ml concentration. You are going to make a series of standards each of 400ul. For a standard of 1.2mg/ml, you will use a pipette to draw up Xul of your 3mg/ml BSA solution, transfer this into a tube and then add enough saline to achieve a total of 400ul.
X = ______ul (round to the nearest microlitre)
160
