General description

Research area: Cancer

Application

Diaphorase from Clostridium kluyveri has been used:
  • in lactate dehydrogenase assay in gill cells.
  • impregnated on the strip for formate dehydrogenase assay.
  • in various assays to oxidate β-NADH or β-NADPH in the presence of an electron acceptor.
  • for semiquinone generation during benzoquinone reduction.
  • for evaluation of glucose uptake in cultured muscle cells.
  • in lactate dehydrogenase cytotoxicity assay.

Biochem/physiol Actions

Diaphorase catalyzes the oxidation of either β-NADH or β-NADPH in the presence of an electron acceptor such as methylene blue or 2,6-dichlorophenolindophenol. Diaphorases that are specific for either β-NADH or β-NADPH are known. The pig heart enzyme of Straub seems to have native diaphorase (β-NADH specific) as well as lipoic and lipoamide dehydrogenase activities.

Unit Definition

One unit of diaphorase will oxidize 1.0 micromole of beta-NADH per minute at pH 7.5 at 25 degrees C, with the corresponding reduction of the appropriate electron acceptor.

Physical form

Supplied as a lyophilized powder containing trehalose.
