Listed are ELISA Kits for the detection of alien, an alias name of COP9 signalosome subunit 2. The human protein, encoded by the gene COPS2, is 443 amino acid residues long and has a mass of 51,597 daltons. However, there are up to 2 reported isoforms. It is a member of the CSN2 family. This protein is reported to have a cytoplasmic and nuclear cellular localization. For this target protein, ELISA kits with the following species reactivities are available: human, mouse, rat, bovine, chicken, primate, guinea pig, and other mammalian. This target may also be known as: COP9 signalosome complex subunit 2, COP9 constitutive photomorphogenic homolog subunit 2, JAB1-containing signalosome subunit 2, TR-interacting protein 15, alien homolog, signalosome subunit 2, and thyroid receptor-interacting protein 15.
