MALDI-MS spectrum (5–10 kDa region) of the hinge peptide fraction from the LC-MALDI dataset of the IgG2 B isoform, obtained from an sDHB matrix preparation. Within this fraction were approximately 40 variants of hinge peptides from all three IgG2 disulfide isoforms. Color-coded IgG2-A (blue), -A/B (red), and -B (green) peaks provide an overview of the isoform-specific hinge peptide fragments in a heterogeneous mixture. “mc” = number of missed cleavage chains in peptides.
