Provided below are ELISA kits targeting renin, a human protein encoded by REN. This protein is 406 amino acids long, with a mass of 45.1 kDa, and is a member of the Peptidase A1 family. 2 isoforms have been identified. This is reported to be a secreted protein. There is a noted implication in Renal tubular dysgenesis. Other alias names for this protein include: angiotensin-forming enzyme, angiotensinogenase, renin precursor renal, and HNFJ2. ELISA kits are available that are reactive to human, mouse, rat, bovine, chicken, primate, plant, and other mammalian variants of the target antigen.
