Description_x000D_ General description_x000D_ 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._x000D_ Application_x000D_ L-Lactic Dehydrogenase from bovine heart has been used:_x000D_ • as a reference standard to measure the LDH (lactic dehydrogenase)_x000D_ • to quench protein-bound NADH in cells_x000D_ • to measure the lactate released by the cells in suspension_x000D_ Packaging_x000D_ 2.5 mL in glass bottle_x000D_ Biochem/physiol Actions_x000D_ LDH (lactic dehydrogenase) helps in the reversible conversion of lactate to pyruvate._x000D_ Also catalyzes the oxidation of other L-2-hydroxymonocarboxylic acids._x000D_ Unit Definition_x000D_ One unit will reduce 1.0 μmole of pyruvate to L-lactate per min at pH 7.5 at 37 °C._x000D_ Physical form_x000D_ Suspension in 2.2 M ammonium sulfate
