A1 Glycan (A2G2S1, G2S1), APTS labeled [Labeled Glycan Standards] (CAT#: CB-P394-K) Datasheet

Product Type
Glycan Standards
Description
Mono-sialylated bi-antennary complex-type N-glycan (oligosaccharide).
Features
Synonyms: A1 N-linked oligosaccharide.
Sources: A1 glycan is found on many mammalian glycoproteins including IgG, gamma globulins, and many serum 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. Contains ammonium salt to stabilise against desialylation.
Molecular Weight: 1933
Purity:> 90% pure as assessed by a combination of 1 H-NMR and HPLC.
Sample
Glycoproteins and glycopeptides containing N-linked glycans
Handling Advice
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.
Storage
Refridgerate (-20°C) both before and after dissolution. This product is stable for at least 5 years as supplied.
Shelf Life
Stability: Stable at least 12 months when stored properly. Several days exposure to ambient tempertures will not reduce activity.
Research Use
For research use only. Not for human or drug use
