Glutamate Decarboxylase 1 (Brain, 67kDa), GAD, Glutamate Decarboxylase 67 KDa Isoform, 67 KDa Glutamic Acid Decarboxylase, GAD-67, EC 184.108.40.206, CPSQ1, SCP, Glutamate Decarboxylase 1 (Brain, 67kD), Glutamate Decarboxylase 1, GAD67, EC 4.1.1, GAD1.
Glutamate Decarboxylase 1 (GAD1) is one of several forms of glutamic acid decarboxylase. GAD1 is responsible for catalyzing the production of gamma-aminobutyric acid from L-glutamic acid. A pathogenic role for the GAD1 enzyme has been identified in the human pancreas since it has been detected as an autoantigen and an autoreactive T cell target type II diabetes. The GAD1 protein may also have a role in the stiff man syndrome. GAD1 enzyme deficiency leads to pyridoxine dependency with seizures. GAD1 also catalyzes the production of GABA.
GAD1 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 247 amino acids (1-224) and having a molecular mass of 27.7kDa.
GAD1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Sterile Filtered colorless solution.
The GAD1 solution (0.5mg/ml) contains 20mM Tris-HCl buffer (pH8.0), 10% glycerol and 0.4M Urea.
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.
Greater than 85% as determined by SDS-PAGE.
