Fig 3. Performance comparison of the enrichment for LMW proteins from human serum using varied methods.
A. The human serum was resolved by 12% glycine SDS-PAGE. B. The human serum was resolved by 12% tricine SDS-PAGE. C. The enrichment of human serum LMW proteins after the process of the optimized-DS method. The volume of serum was used as indicated on the figure.
