Figure 6. MS/MS spectrum of tryptic fragments

A: MS/MS spectrum of a tryptic fragment having a mass of 899.48 (MS/MS of 450, 2⁺), identifying a sequence of KQVSGPER by the y ions. B: MS/MS spectrum of a tryptic fragment having a mass of 1,139.62 (MS/MS of 570, 2⁺), identifying a sequence of EEKPAVTAAPK by the y ions. C: MS/MS spectrum of a tryptic fragment having a mass of 2,014 (MS/MS of 1008, 2⁺), identifying a sequence of PLTITSSLSSDGVLTVNGPR by the b and y ions.
