Assigning function to the structure of HIV and SARS-CoV-2 glycan shields

Weston Struwe of the University of Oxford describes the analysis of HIV and SARS-CoV-2 viral spikes and illustrate how glycomics/ glycoproteomics datasets can inform on their structural assembly and biological functions.

Three Channel Charge Deconvolution

There are two quite different methods for determining the charge of m/z peaks:  peak spacing for isotope-resolved masses, and ratio relations among peaks for isotope-unresolved masses. Most software uses one method or the other, but Protein Metrics Intact Mass can use both information channels simultaneously, as well as a third channel...

Tackling the Glycan Isomer Challenge for your Biotherapeutics

As minor changes to production processes can influence both glycan structure and composition, glycans must be monitored. However, characterization of N-linked glycosylation is analytically challenging due to innate glycan microheterogeneity.
