SugarQb is a collection of software tools (Nodes) which enables the automated identification of intact glycopeptides from HCD‐MS/MS data sets, using common MS/MS search engines (e.g. MASCOT, SEQUEST‐HT) in the Proteome Discoverer 1.4 environment.


SugarQb is freely available to all researchers.

For further information on the algorithm, please refer to the corresponding publication
Stadlmann J., Taubenschmid J., et al. Comparative glycoproteomics of stem cells identifies new players in ricin toxicity, Nature (2017).

We also provide a quick guide on how to download, install and test SugarQb.
