Figure 7

Fibrinogen peptide MS/MS data. Figure 7a shows one of the MS/MS spectra used to identify the m/z 1885 SELDI peak as the fragment of fibrinogen DEAGSEADHEGTHSTKRG (3+ parent ion, 1+ fragments). Figure 7b shows MS/MS analysis of synthetic DEAGSEADHEGTHSTKRG. Figure 7c shows MS/MS analysis of synthetic DEAGSEADHEGTHSTKRG with 13C + 15N labelled alanine at positions 3 and 7 and glycine at positions 4 and 11. All spectra obtained by LC-MS/MS as described in the Methods section.
