Fig 1. Fibrinopeptide A and its degradation products.
Peak areas obtained from extracted ion chromatograms of triply protonated murine fibrinopeptide A (DTEDKGEFLSEGGGVR, purple; m/z 565.9) and its triply protonated degradation products TEDKGEFLSEGGGVR (green; m/z 527.6) and EDKGEFLSEGGGVR (white; m/z 493.9). Six to nine samples were analyzed for each matrix (blood, B; direct serum, DS; activated serum, AS) and time point.
