Description
GALNT1 produced in Sf9 Insect cells is a single, glycosylated polypeptide chain containing 528 amino acids (41-559a.a.) and having a molecular mass of 60.4kDa. GALNT1 is expressed with an 9 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
Introduction
Polypeptide N-Acetylgalactosaminyltransferase 1 (Galnt1) is a part of the UDP-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase (GalNAc-T) family of enzymes. The initial reaction in O-linked oligosaccharide biosynthesis is catalyzed by Glant1, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Moreover, Galnt1 is implicated in the glycosylation of proteins vital for bone formation for instance osteopontin and bone sialoprotein.
Purification Method
/
Physical Appearance
Sterile filtered colorless solution.
Formulation
GALNT1 protein solution (1mg/ml) contains 20mM Tris-HCl buffer (pH 8.0) containing 0.1M NaCl and 10% glycerol.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.
Purity
Greater than 90.0% as determined by SDS-PAGE.
Biological Activity
The specific activity which is defined as the amount of enzyme that transfer 1.0 pmole of GalNAc from UDP-GalNAc to peptide EA2 per minute at pH 8.0 at 37C is > 300 pmol/min/ug.
