Introduction
GLUL catalyzes the synthesis of glutamine from glutamate and ammonia.
Glutamine is a major source of energy and that takes part in cell proliferation, inhibition of apoptosis, and cell signaling. GLUL is expressed during early fetal stages, and has a role in maintaining body pH by removing ammonia from circulation.
Mutations in GLUL gene are related with congenital glutamine deficiency.
Description
GLUL Recombinant Human produced in E.Coli is a single, non-glycosylated polypeptide chain containing 393 amino acids (1-373 a.a.) and having a molecular mass of 44.2 kDa. The GLUL is fused to a 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile filtered colorless solution.
Formulation
GLUL Human solution containing 20mM Tris-HCl pH-8, 5mM DTT, 0.2M NaCl & 20% 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
Specific activity is > 2,800 pmol/min/ug, and is
defined as the amount of enzyme that convert 1.0 pmole of L-glutamate to
L-glutamine per miunte at pH 7.5 at 37C in coupled system with PK/LDH.
