Proteomic analysis of the proteins from (−) and (+) cells. The Coomassie-stained SDS-PAGE gel (as the one shown in Figure
1A) was divided in gel pieces and then subjected to LC-MS/MS analysis, as described in the methods section. Venn diagrams in A &B show the number of proteins identified per condition (from both (−) and (+) cells), as well as the number of proteins that are common or different in the (−) and (+) cells. Here we show the results from experiment 1 in A and experiment 2 in B.
