LDH-A, GSD11, LDH1, LDHM, PIG19, EC 220.127.116.11, lactate dehydrogenase M, LDH-M, LDH-1, L-lactate dehydrogenase A chain, LDH muscle subunit, Renal carcinoma antigen NY-REN-59, Cell proliferation-inducing gene 19 protein, LDHA.
D-lactate dehydrogenase or ldhA is an enzyme, part of the D-lactate dehydrogenase protein family. IDHA is a cytochrome that enhances the catalyzation of D-lactate dehydrogenase ldhA reaction. This enzyme has 2 substrates ((D) -lactate & ferricytochrome c), thus, it has 2 end products (pyruvate & ferrocytochrome c).
LDHA E.Coli Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 353 amino acids (1-329) and having a molecular mass of 39.1 kDa.
LDHA E.Coli is fused to a 24 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.
LDHA E.Coli protein (1mg/ml) is formulated in 20mM Tris-HCl buffer (pH 8.0), containing 100mM NaCland 10% glycerol.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 95.0% as determined by SDS-PAGE.
Specific activity is > 200unit/mg. 1 unit converts 1.0 umole of pyruvate to L-lactate and beta-NAD per minute at pH 7.5 at 37˚C
