Figure 2From: Comparison of two label-free global quantitation methods, APEX and 2D gel electrophoresis, applied to the Shigella dysenteriae proteome Annotated proteome map of 2D gel. SD1 proteins were analyzed by 2-DE in the pH range 4 – 7. 271 proteins mapped to the gel by 2-DE/MS are represented by spot numbers. 2-DE protein abundances of 255 proteins matched to unique spots were correlated with APEX abundances.Back to article page
