The disialylated core 2 glycan consists of a galactose molecule linked β-3 to GalNAc similar to the core 1 glycan. NeuAc sialic acid is linked alpha-3 to the galactose while the GalNac is attached to GlcNAc-Gal-NeuAc. This glycan is labeled with the fluorescent 2-AB molecule.

Description :2-AB labeled disialylated core 2 O-linked glycan, C2S(3,3)2.

Amount: 100 picomoles

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

Purity :>90% pure as assessed by a combination of CE and HPLC.

Storage: Keep at -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. Minimize exposure to elevated temperatures or extremes of pH.

Safety ：This product is non-hazardous and has been purified from synthetic sources certified to be free of all hazardous material including pathogenic biological agents.
