A. Venn diagram for the overlap of identified LMW proteins from the same sample processed by gel-filter, glycine SDS-PAGE and optimized-DS methods. B. Molecular weight distribution of identified LMW proteins from these three approaches. C. The distribution of identified peptides from the LMW proteins after the process of these three approaches. D. Abundance analysis of commonly identified 134 LMW proteins from these three strategies. E. Sequence coverage distribution of the commonly identified LMW proteins from these three methods.(*:P < 0.05, **:P < 0.01)
