Beam type tandem mass spectra of the AGC(cam)LIGAEHVNN(dea)SYEC(cam)DIPIGAGIC(cam)ASYQTQTNSPR (SA1Hex2HexNAc2) O-glycopeptide with assigned extended core-1 and core-2 structures. The structures are characterized by the following fragments: (A) oxonium ions 366 and 657, generated from both core-1 and core-2 structures; (B) oxonium ion 407 specific for the core-2 and ions 528 and 819 specific to the extended core-1 structure; and (C) oxonium ion 1022 correspoding to the detached intact glycans.
