Services We Provide
National Glycoscience Resource NGR@CCRC
Through the “National Glycoscience Resource” program (NIH grant R24GM137782) we provide services and training for the structural characterization of all types of glycoconjugates to the greater biomedical scientific community including universities, minority serving institutions, federal agencies, biotechnology, and pharmaceutical industries. Our plant characterization projects are supported by an additional grant from the Department of Energy “Center for Plant and Microbial Complex Carbohydrates” (DE-SC0015662). The particular combination of technologies applied for this purpose will depend on the specific structural information desired by the user and will be determined individually after discussion with Dr. Azadi.

New paper out in Carbohydrate Polymers!
We present the most detailed structural analysis of RG-I in Arabidopsis thaliana to date using NMR & MS.
Key findings:
3-O-acetylation on ~10% of Rha residues
Unique β-1,6-galactan terminations
Minor GalA O-acetylation

New Publication Alert!
New from our lab: a comprehensive review of methods for determining molecular weight in insoluble polysaccharides—a major analytical challenge. We explore both intact and non-intact strategies, plus the role of molecular modeling.

New Publication Alert!
Exciting! Our collaboration with Matt Delissa has been published in Nature Communications!
This study marks a major step forward in antibody engineering—demonstrating how a bacterial enzyme can glycosylate human IgG in E. coli. This breakthrough opens the door to more accessible and cost-effective production of therapeutic antibodies with functional glycosylation. Xu Yang from our group performed glycoproteomic tandem MS analysis of the protein samples. The LC-MS/MS data were instrumental in confirming glycosylation of the native QYNST sequon in the hinge-Fc region by DmPglB.
