The comparison of identified human serum proteins from gel-filter method and the publically available largest datasets.

A. Venn diagram for all of the proteins identified from three methods, including gel-filter, 12% glycine SDS-PAGE and the optimized-DS methods. B. Venn diagram showing the overlap between proteins identified from gel-filter method and the collected datasets for all of the published serum proteomics studies by Farrah et al. C. Venn diagram showing the overlap between proteins identified from all of the three methods used in our study and the collected datasets as in B. D. Venn diagram showing the overlap of proteins identified for gel-filter method and other three serum LMW proteomics studies. All proteins were converted to Gene symbol ID for comparison.
