Positive ion nHPLC/ESI/MS spectra of a peptide with high mannoses and the anomalous cleavage partial peptides containing high mannose consensus sites a) N328, b) N154/160′, c) N358′, and d) N370. The ′ indicates a partial peptide. For figure clarity, the peaks corresponding to high mannose consensus site N304 are labeled with an *. Other tryptic peptides are labeled. Peaks that were not identified are labeled with a †. The mannoses are labeled depending on the number present, where Man=mannose. The superscripted number is the charge state.
