Provided below are ELISA kits targeting caspase 1, a human protein encoded by CASP1. This protein is 404 amino acids long, with a mass of 45.2 kDa, and is a member of the Peptidase C14A family. 5 isoforms have been identified. This is reported to be a cytoplasmic and membrane protein. Other alias names for this protein include: CASP1 nirs variant 1, IL-1 beta-converting enzyme, IL1B-convertase, caspase 1 apoptosis-related cysteine peptidase, interleukin 1-B converting enzyme, ICE, and IL1BC. ELISA kits are available that are reactive to human, mouse, rat, bovine, chicken, primate, guinea pig, fish, plant, and other mammalian variants of the target antigen.
