WebMar 18, 2015 · They found that HCD was better for matching glycopeptide identities than ETD, because the technique produced greater quantities of glyco-oxonium ions for onward analysis in the CID/ETD MS/MS step. Although they considered that ETD did not function well for N-glycosylation analysis, it did improve findings in O-glycosylation characterization. WebIntegrated with de novo sequencing Supports all types of fragment ions: CID, HCD, ETD/ECD, and EThcD Protein Identification with MS/MS Bottom-up proteomics (LC-MS/MS) serves as the basis for much of the protein research today. There are a variety of algorithms for the interpretation of peptide fragmentation data.
