NGA2F glycan (FA2, G0F)
Biantennary N-glycan that contains terminal N-acetylglucosamine residues, and fucosylation on the core GlcNAc. (size: 20µg) m/z: 1462.5444
NGA2F: Asialo-, agalacto-, core-fucosylated bi-antennary complex-type N-glycan (oligosaccharide). NGA2F is the agalacto- substructure of NA2F (G2F) glycan and is found on many mammalian glycoproteins including human IgG and is a substructure of bi-antennary N-linked oligosaccharides such as A2F, A1F, and NA2F which are widely found on glycoproteins. This product is typically purified from the oligosaccharide pool released from porcine serum usually by enzymatic release (but also chemical hydrolysis) using a combination of HPLC and glycosidase digestion. NGA2F can also be directly released from Human IgG using HPLC without any glycosidase digestion.
Product Specification

Description: G0F: Asialo-, agalacto-, core-fucosylated bi-antennary complex-type N-glycan (oligosaccharide). NGA2F is the agalacto- substructure of NA2F (G2F) glycan.
Molecular Weight: 1463
Purity: >90% pure as assessed by a combination of 1 H-NMR and HPLC
Sources: The NGA2F (G0F) glycan is found on many mammalian glycoproteins including human IgG and is a naturally occurring oligosaccharide or a substructure of bi-antennary N-linked oligosaccharides such as A2F, A1F, and NA2F which are also widely found on glycoproteins. This product is typically purified from the oligosaccharide pool released from porcine serum usually by enzymatic release (but also chemical hydrolysis) using a combination of HPLC and glycosidase digestion. NGA2F can also be directly released from Human IgG using HPLC without any glycosidase digestion.
Form: Dry. Dried by centrifugal evaporation from an aqueous solution. No salts.
Storage: -20˚C both before and after dissolution. This product is 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 oligosaccharides into the 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 purified from natural sources certified to be free of all hazardous material including pathogenic biological agents.
