Ldh 50ml Kit

Lactate dehydrogenase (LDH) is present in every cell, it is a tetramere molecule which is a combination of two different tissue components (M-muscle, H-heart). There are five different isoenzymes: LDH-1: LDH-2: LDH-3: LDH-4: LDH-5 = 20:34:23 12: 11. The serum activity is mainly composed of LDH-1, LDH-2 derived from the myocardium and red blood cells, and LDH-5 derived from the liver. The activities of isoenzymes are different in cases of certain substrates. The inhibitors and pH sensitivities are different. The various fractions were determined using chromatography in the past but more recently electrophoresis is the method of choice. The ratio of isoenzymes indicates certain disease states. The enzyme activity significantly increases 8-12 hours following a myocardial infarction and declines after 4-5 days. There is an increase in liver diseases, in certain anaemia and tissue injuries. The enzyme catalyses the Pyruvate / Lactate transformation at optimal pH.
