LDH ELISA kits are assays designed to measure levels of the enzyme lactate dehydrogenase in biological samples, such as plasma, serum, culture extracts, and cell lysates. LDH facilitates the conversion of pyruvate to lactate and vice versa while interconverting NAD+ and NADH. It plays a crucial role in glycolysis, converting pyruvate to lactate in anaerobic conditions. Widely expressed in tissues like blood cells and heart muscle, LDH serves as a marker for tissue damage, making it useful in diagnosing injuries and conditions such as heart failure. LDH is a protein complex consisting of four subunits; the two most common are encoded by the genes LDHA and LDHB.
