NGA2F 2-AA Glycan Synonyms NGA2F N-linked oligosaccharide, G0F
Description Asialo-, agalactosylated core-fucosylated bi-antennary complex-type N-glycan (oligosaccharide).
Sources NGA2F glycan 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 thyroglobulin by hydrazinolysis using a combination of HPLC and glycosidase digestion.
Form Dry. Dried by centrifugal evaporation from an aqueous solution.
Molecular Weight 1584
Number of Samples Typically, 100 fmol to 10 pmol of the NGA2F 2-AA glycan can be detected, dependent on the sensitivity of the fluorometer, HPLC or mass spectrometer.
Amount of Sample 100 pmol
Structural Integrity Determined by MALDI mass spectrometry and HPLC.
Labeling Selectivity Essentially stoichiometric labelling. One fluorophore molecule covalently bonded to each glycan.
Detection Fluorescence detection: 360 nm excitation wavelength, 425 nm emission wavelength.
Purity >90% pure as assessed by a combination of 1 H-NMR and HPLC.
Storage -20˚C both before and after dissolution. This product is stable for at least 5 years as supplied. View Certificate of Stabilty
Shipping The product can be shipped at ambient when dry.
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.
