A mixture of APTS labelled fucosylated bi-antennary complex-type N-glycans (oligosaccharides) released from human IgG antibody glycoprotein. This product consists of purified N-glycans that have been released from human IgG antibody glycoprotein by N-mode hydrazinolysis, labelled with 8-aminopyrene-
The APTS IgG library is a mixture of nonfucosylated and fucosylated, bi-antennary glycan standards with variable sialylation released from human IgG antibody glycoprotein. They are available unlabeled and labeled with a variety of tags.
We also supply an IgG glycoprotein standard for use during glycan release and labeling.
"Glycosylation can significantly affect the in vivo safety and efficacy profiles of therapeutic recombinant monoclonal antibodies (rMAbs). In particular, glycans can have a marked influence on IgG Fc effector functions and changes in antibody glycosylation are a major cause of batch-to-batch variability during production. For these reasons, it is essential to measure and control antibody glycosylation accurately and reliably." This introduction was copied from Dr. Daryl Fernandes’ article Demonstrating Comparability of Antibody Glycosylation during Biomanufacturing
Sources: The IgG glycan library in this products is released from an IgG standard that is purified from human serum. IgG exists in a variety of glycoforms containing bi-antennary oligosaccharides with variable sialylation.
Form: Dry. Dried by centrifugal evaporation from an aqueous solution.
Amount supplied 10 pmols
Storage: -20˚C both before and after dissolution. The products are stable for at least 5 years as supplied.
Shipping: The product can be shipped at ambient when dry. After dissolution, ship on dry ice.
Handling: Allow the unopened vial to reach ambient temperature and tap unopened on a solid surface to ensure that most of the lyophilized material is at the bottom of the vial. Gently remove the cap, add the desired volume of reconstitution medium, re-cap and mix thoroughly to bring all the oligosaccharide into solution. For maximal recovery of oligosaccharide, ensure that the cap lining is also rinsed and centrifuge the reconstituted vial briefly before use. Ensure that any glass, plasticware or solvents used are free of glycosidases and environmental carbohydrates. Minimise exposure to elevated temperatures or extremes of pH. High temperatures and low pH will cause desialylation. High pH will cause epimerisation of the reducing terminus GlcNAc.
Safety: This product is non-hazardous and has been purified from natural sources certified to be free of all hazardous material including pathogenic biological agents.
