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

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

For use in enzymatic determination of lactate or pyruvate.

Packaging

2.5 mL in glass bottle

Biochem/physiol Actions

LDH (lactic dehydrogenase) helps in the reversible conversion of lactate to pyruvate.
Also catalyzes the oxidation of other L-2-hydroxymonocarboxylic acids.

Unit Definition

One unit will reduce 1.0 μmole of pyruvate to L-lactate per min at pH 7.5 at 37 °C.

Physical form

Suspension in 2.2 M ammonium sulfate
