Product Specifications

FA2BG1 2-AA Glycan Synonyms FA2BG1 N-linked oligosaccharide, FA2G1 with bisecting GlcNAc, G1F with bisecting GlcNAc

Description Asialo-, monogalactosylated with a bisecting GlcNAc bi-antennary complex-type N-glycan (oligosaccharide).

Form Dry. Dried by centrifugal evaporation from an aqueous solution.

Number of Samples Typically, 100 fmol to 10 pmol of the FA2BG1 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.

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.
