Figure 4From: Peptides OFFGEL electrophoresis: a suitable pre-analytical step for complex eukaryotic samples fractionation compatible with quantitative iTRAQ labeling Average distribution of charged amino acids per peptide in each OFFGEL fraction obtained for secretome separation. (A) Average number of acidic amino acids (aspartic acid (D) and glutamic acid (E)), and basic amino acids (lysine (K) and arginine (R)).(B) Average number of cysteine (C), histidine (H) and tyrosine (Y) charged amino acids.Back to article page
