There are a number of ELISA Kits available for the measurement of hydroxysteroid (17-beta) dehydrogenase 11, another term for the human protein, hydroxysteroid 17-beta dehydrogenase 11. Other synonyms may include: 17-beta-hydroxysteroid dehydrogenase type XI, CTCL tumor antigen HD-CL-03, CTCL-associated antigen HD-CL-03, dehydrogenase/reductase SDR family member 8, and retinal short-chain dehydrogenase/reductase 2. It is encoded by the HSD17B11 gene to yield a protein 300 amino acids in length and 32.9 kDa in size. The protein, an enzyme, is categorized into the Short-chain dehydrogenases/reductases (SDR) family, 17-beta-HSD 3 subfamily. Versions of hydroxysteroid (17-beta) dehydrogenase 11 are present in other organisms, including: Mouse, Rat.
