Comparison of the differential proteins identified by 2-DE and label-free LC–MS analysis. a Venn diagram showing the distribution of 142 proteins. The large pie chart represents the proteins identified by the label-free LC–MS-based technique, and the small pie chart represents the proteins identified by the 2-DE technique. The numbers indicate the protein numbers in each partition. b Qualitative comparison of the protein numbers in veliger larvae. A total of 142 differentially abundant proteins are grouped into 29 categories according to their biological functions. Color codes are the protein numbers identified by differential analysis
