Glutamic-Pyruvate Transaminase 2 (GPT2) catalyzes the reversible transamination among alanine and 2-oxoglutarate to create pyruvate and glutamate. GPT2 expressed mainly in muscle, fat and kidney and participates in the intermediary metabolism of glucose and amino acids.
GPT2 Mouse Recombinant produced in E. coli is a single polypeptide chain containing 522 amino acids (1-522) and having a molecular mass of 60.1 kDa. Mouse GPT2 is fused to a 21 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
The GPT2 solution (1mg/1ml) contains 20mM Tris-HCl buffer (pH 7.5), 20% glycerol, and 2mM DTT.
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.
Greater than 50units/mg, and is defined as the amount of enzyme that cleaves 1umole of L-Alanine to L-Glutamate per minute at pH7.5 at 37℃.
