Recombinant humaan lactaatdehydrogenase B/LDHB-eiwit

LDHB, also known as L-lactate dehydrogenase B chain isoform LDHB, is a member of the lactate dehydrogenase family. It is an oxidoreductase which catalyses the interconversion of pyruvate and lactate with concomitant interconversion of NADH and NAD+. As this protein can also catalyze the oxidation of hydroxybutyrate. The LDH family consists of three members, LDH-A, LDH-B and LDH-C. LDHs function as powerful markers for germ cell tumors. Recombinant human LDHB protein was expressed in E. coli and purified by using conventional chromatography techniques.

Specific activity is > 300 units/mg, in which one unit will convert 1.0 umole of pyruvate to L-lactate and beta-NAD per minute at pH 7.5 at 37C.
