Effects of pH on SEC spectrum of BSA solution (A) and relative contents of total aggregates, dimer and trimer, nonamer and insoluble aggregates (B) at BSA concentration of 0.30 g/L. The peaks at about 8.95 mL, 8.01 mL, 7.46 mL and 5.90 mL correspond to monomer, dimer, trimer and nonamer of BSA, respectively.
