Figure 1From: Comparison of two label-free global quantitation methods, APEX and 2D gel electrophoresis, applied to the Shigella dysenteriae proteome Flow chart of data analysis approach. The data analysis approaches employed for the LC-MS/MS-APEX and 2-DE/MS methodologies are shown here. The numbers in both approaches represent the average of three replicate experiments. 1148 SD1 proteins were quantitated by LC-MS/MS-APEX and 271 proteins from 2D gels.Back to article page
