Premier Biosoft has introduced version 2.92 of its MS data tool, SimGlycan. This program now includes comprehensive support to perform multi-stage/sequential mass spectrometry data analysis which involves re-fragmentation of product ions. Multi-stage mass analysis provides structural information that is useful in structure elucidation of metabolites, glycopeptides and glycans. It aids in discrimination of glycans which have similar characteristic fragment ions at MS/MS level and resolves heterogeneity of carbohydrate distribution and branching patterns of complex glycans such as isobaric isomers.
