Merck, L3916-2.5ML, L-Lactic Dehydrogenase from bovine heart

General description
LDH (lactic dehydrogenase) is a glycolytic enzyme. It is found in skeletal muscle, heart, liver, kidneys, brain, lungs and red blood cells. It comprises of five isoenzyme forms. LDH possess a tetrameric structure.
Application
For use in enzymatic determination of lactate or pyruvate.
L-Lactic Dehydrogenase from bovine heart has been used:
as a reference standard to measure the LDH (lactic dehydrogenase)
to quench protein-bound NADH in cells
to measure the lactate released by the cells in suspension

Biochem/physiol Actions
Also catalyzes the oxidation of other L-2-hydroxymonocarboxylic acids.
LDH (lactic dehydrogenase) helps in the reversible conversion of lactate to pyruvate.
Physical form
Suspension in 2.2 M ammonium sulfate
Other Notes
One unit will reduce 1.0 μmole of pyruvate to L-lactate per min at pH 7.5 at 37 °C.
