Enrichment analysis of functional protein groups identified by iTRAQ proteomics using amnion extracts derived from fresh or cryopreserved human amnion. Enriched GO analyses were performed and the top 10 enriched functional classes from C-AME proteins that were either of comparable abundance, enriched or reduced relative to F-AME were plotted. The number of discrete proteins for each functional class is shown in parenthesis beside the functional class names. Fold enrichment for each functional class relative to the prevalence of that functional class in the total human proteome is listed on X-axis
