Anti-HSD17B2 antibodies are used in the immunodetection of the protein hydroxysteroid 17-beta dehydrogenase 2. In humans, the canonical protein has a reported length of 387 amino acid residues and a mass of 42.8 kDa. Its subcellular localization is in the ER. It is notably expressed in the placenta. A member of the Short-chain dehydrogenases/reductases (SDR) protein family, HSD17B2 is known to catalyze the NAD-dependent oxidation of the highly active 17beta-hydroxysteroids, such as estradiol (E2), testosterone (T), and dihydrotestosterone (DHT), to their less active forms and thus regulates the biological potency of these steroids. Synonyms for this target antigen include HSD17, SDR9C2, 17-beta-hydroxysteroid dehydrogenase type 2, 17-beta-HSD 2, 20 alpha-hydroxysteroid dehydrogenase, and EDH17B2. HSD17B2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of HSD17B2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Flow Cytometry and Immunohistochemistry are also common applications.
