View product documentation
M3N2 Glycan Synonyms: conserved trimannosyl core, chitobiose, M3, Man-3
Description: Pentasaccharide core complex-type N-glycan (oligosaccharide).
Molecular Weight: 911
Purity: >90% pure as assessed by a combination of 1 H-NMR and HPLC.
Sources: M3N2 glycan is a substructure common to most of the N-linked oligosaccharides which are widely are found on glycoproteins. This product is typically purified from the oligosaccharide pool released from bovine serum by hydrazinolysis using a combination of HPLC and glycosidase digestion.
Form: Dry. Dried by centrifugal evaporation from an aqueous solution.
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 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.
HPLC Analysis of Glycans
LudgerPure unlabeled glycans and LudgerTag labeled glycans may be separated and analysed by a variety of HPLC (high pressure liquid chromatography) methods using LudgerSep™ HPLC columns.
