Lactate dehydrogenase (LDH) is an oXidoreductase. LDH catalyzes the conversion of lactate to pyruVIc acid and back, as it converts NAD+ to NADH and back. LDH is composed of four subunits (tetramer). The two most common subunits are the LDH-M and LDH-H protein. LDH is released into the blood by cells after tissue damage or erythrocyte hemolysis. EXtracellular LDH actIVIty is used to detect cell damage or cell death.
It isrecommended to take 2~3 samples with expected large difference to dopre-experiment before formal experiment and dilute the sample according to theresult of the pre-experiment and the detection range (0.2-55.6King unit/100 mL. Therecommended dilution factor for different samples is as follows (for reference only): Sample type Dilution factor, Human serum Human urine Rat serum Cellular supernatant 10% Mouse kidney tissue homogenization 30-50, 10% Mouse liver tissue homogenization HePG2 cell 10% Mouse brain tissue homogenization 1. Note:Thediluentisnormalsaline(0.9%NaCl)orPBS(0.01M,pH7.4).
