Anti-HIBADH antibodies are used in the immunodetection of the protein 3-hydroxyisobutyrate dehydrogenase. In humans, the canonical protein has a reported length of 336 amino acid residues and a mass of 35.3 kDa. Its subcellular localization is in the mitochondria. It is notably expressed in skin fibroblasts. It is a member of the HIBADH-related protein family. HIBADH is also used as a cellular marker for characterizing astrocytes. Synonyms for this target antigen include 3-hydroxyisobutyrate dehydrogenase, mitochondrial, 3'-hydroxyisobutyrate dehydrogenase, epididymis secretory sperm binding protein, and NS5ATP1. HIBADH gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some HIBADH antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, Western Blot is also a common application.
