Glyco-Peakfinder
Introduction
The "Glyco-Peakfinder" is a tool for fast annotation of glycan MS spectra. MS-profiles, MSn spectra with different types of ions (glycosidic cleavages and/or cross-ring cleavages) can be calculated in parallel. The option of detecting differently- and/or multiply-charged ions in one calculation cycle provides a fast and complete annotation of the whole spectrum. All the additional options of "Glyco-Peakfinder" (e.g. calculation of modifications either at the reducing end or within the sequence ) increase the field of application from native glycans to a variable set of glycoconjugates. The results from "Glyco-Peakfinder" can be used for advanced database searches in GLYCOSCIENCES.de.
