Anti-SDHB antibodies are used in the immunodetection of the protein succinate dehydrogenase complex iron sulfur subunit B. In humans, the canonical protein has a reported length of 280 amino acid residues and a mass of 31.6 kDa. Its subcellular localization is in the mitochondria. It is notably widely expressed in many tissue types. A member of the Succinate dehydrogenase/fumarate reductase iron-sulfur protein family, SDHB is known to be involved with electron transport. The SDHB gene has been associated with the disease, Pheochromocytoma. Synonyms for this target antigen include CWS2 and IP. SDHB gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 210 citations in the literature describe the use of SDHB antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
