Description_x000D_ General description_x000D_ Anti-AKR1C3 antibody, Mouse monoclonal (humanα - hydroxysteroid dehydrogenase, type 2,3; 17β- hydroxysteroid dehydrogenase, type 5) (mouse IgG1 isotype) is derived from the hybridoma NP6.G6. A6 produced by the fusion of mouse myeloma cells (SP20 cells) and splenocytes from BALB/c mice immunized with human AKR1C3 protein. Oxidoreduction of natural and foreign substrates is performed by three enzymes superfamilies, one of them being the AKRs (aldo-keto reductases) family. This family contains 114 proteins that are expressed in prokaryotes and eukaryotes and is divided into 14 subfamilies (AKR1-AKR14). The AKR1 family is the largest among the different fourteen families and contains the aldose reductases, aldehyde reductases, hydroxysteroid dehydrogenases, and steroid 5 β-reductases. AKR1Cs are expressed in many tissues._x000D_ Immunogen_x000D_ human AKR1C3 protein._x000D_ Application_x000D_ Anti-AKR1C3 antibody, Mouse monoclonal has been used in_x000D_ • western blotting_x000D_ • immunohistochemistry_x000D_ • enzyme linked immunoassay (ELISA)._x000D_ Target description_x000D_ AKR1C3, aldo-keto reductase family 1, member C3 (3-α hydroxysteroid dehydrogenase, type II), encodes a member of the aldo/keto reductase superfamily, which consists of more than 40 known enzymes and proteins.

AKR1C1-4 isoforms also display 3α[17β]-hydroxysteroid oxidase activity using 3α-Diol as a substrate, in vitro. In non-small cell lung carcinoma, AKR1Cs expression is dramatically increased. Due to their product profile and discrete tissue localization, they may regulate the level of active androgens, estrogens, and progestins in target tissues.
