Description: Asialo-, monoglactosylated bi-antennary complex-type N-glycan (oligosaccharide). This glycan is a mixture of the two possible galactosylated isomers.
Sources: FA2G1 glycan is found on several mammalian glycoproteins including asialo serum transferrin and fibrin. 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.
Molecular Weight: 1624
Purity: > 90% pure as assessed by a combination of 1 H-NMR and HPLC.
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 the FA2G1 Glycan
LudgerPure and LudgerTag labeled glycan mixtures may be separated and analysed by a variety of HPLC (high pressure liquid chromatography) methods using LudgerSep HPLC columns.
The LudgerSep columns are are available for the following applications: Separation of charged and neutral glycans via anion exchange columns: LS-C3-7.5×75 LudgerSep C3 – 7.5x75mm LS-C2-4.6×50 LudgerSep C2 – 4.6x50mm Profile analysis of neutral and charged glycans via normal phase columns: LS-N2-2.0×250 LudgerSep N2 – 2.00x250mm LS-N2-4.6×250 LudgerSep N2 – 4.6x250mm LS-N1-4.6×250 LudgerSep N1 – 4.6x250mm
The LudgerSep N2 columns are an especially powerful tool for the purification and analysis of LudgerTag labeled oligosaccharides from complex glycan mixtures. Please contact us for advise regarding your particular application.
