The microplate assay ab140361 is used to determine Lactate dehydrogenase B activity (LDHB) in a sample utilizing the immunocapture technique. The specific native LDHB enzyme is immune-captured within the wells of the microplate and activity is determined by following the production of NADH catalyzed by the enzyme. The generation of NADH is coupled to the 1:1 reduction of a reporter dye to yield a colored (yellow) reaction product whose concentration can be monitored by measuring the increase in absorbance at 450 nm (Dye molar extinction coefficient - 37000 M-1 cm-1). The immune-capture based activity assay kit contains all the required reagents for a fast and simple measurement of LDHB activity in a whole cell extract, tissue homogenate, or serum.
Functional lactate dehydrogenase are homo or hetero tetramers composed of M and H protein subunits encoded by the LDHA and LDHB genes, respectively. The major isozymes of skeletal muscle and liver has four muscle (M) subunits; while the main isozymes for heart muscle contains four (H) subunits. The other variants contain both types of subunits. Elevated levels of LDH indicate tissue breakdown in hemolysis. LDH can be used as a marker of myocardial infarction, peaking at days 3 and lasting through day 10. Other disorders indicated by elevated LDH include cancer, meningitis, encephalitis, acute pancreatitis, and HIV. Defects in LDHB are a cause of hereditary LDHB deficiency; however LDHB deficiency is usually asymptomatic.
