Anti-Lactate Dehydrogenase B antibodies are used for the immunodetection of the protein encoded by the LDHB gene. In humans, the canonical protein has a reported length of 334 amino acid residues and a mass of 36.6 kDa. Its subcellular localization is in the mitochondria and cytoplasm. It is reported to be highly expressed in the aerobic tissues such as cardiac muscle. A member of the LDH protein family, it is known to be involved with metabolic processes. The gene encoding this protein is implicated in Lactate dehydrogenase B deficiency. Other names for this target antigen include LDH-H, LDHBD, TRG-5, L-lactate dehydrogenase B chain, LDH heart subunit, and HEL-S-281. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 110 citations in the literature describe the use of Lactate Dehydrogenase B antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
