Malate Dehydrogenase 1 Human Recombinant ( MDH1 Human )

Data sheet

Formulation

The MDH1 1mg/ml protein solution contains 20mM Tris-HCl pH-8, and 10% glycerol.

Purity

Greater than 95.0% as determined by SDS-PAGE.

Description

MDH1 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 342 amino acids (1-334 a.a.) and having a molecular mass of 37.4 kDa. The MDH1 is fused to an 8 amino acid His tag at C-terminus and purified by conventio

Protein Background

MDH1 catalyzes the reversible oxidation of malate to oxaloacetate, using the NAD/NADH cofactor system in the citric acid cycle. MDH1 is abundantly found in the cytoplasm and is involved in the malate-aspartate shuttle that functions in the metabolic coord

Expression host

Escherichia Coli.

Synonyms

MDH-s, MDHA, MOR2.

Stability

MDH1 although stable 4°C for 4 weeks, should be stored desiccated below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
