Abstract: Kuznetsov AV, Gnaiger E. Laboratory protocol: Lactate dehydrogenase. Cytosolic marker enzyme. Mitochondr Physiol Network 08.18.

Lactate dehydrogenase (EC is an enzyme, which catalyzes the last step in glycolysis. LDH is a soluble enzyme and localized in the cytosol (cytoplasm). LDH, therefore, is used as a quantitative marker enzyme for the intact cell, its activity providing information on cellular glycolytic capacity (Renner et al, 2003). Measurement of LDH release (leakage) is an important and frequently applied test for cellular membrane permeabilization (rupture) and severe irreversible cell damage. LDH leakage normally correlates well with CK release and the trypan blue viability test.
