WebThe only observed degradation product, through permethylation and MS analysis, was a sugar lactone/acid derivative with the reducing end oxidized. Author Manuscript Coupled with the evidence on similarity of N-glycans produced by PNGase F or ORNG above, these results indicate that under controlled conditions, glycans are stable to NaClO treatment. WebJan 1, 2013 · Permethylation, which converts the free hydroxyl groups in glycans to methoxy groups, is widely used because of its simplicity and robustness . The conversion greatly enhances the ionization efficiency and sensitivity of mass spectrometric analysis. Permethylation stabilizes sialic acids, enabling the simultaneous analysis of neutral and …
