Listed are ELISA Kits for the detection of M/NEI, an alias name of serpin family B member 1. The human protein, encoded by the gene SERPINB1, is 379 amino acid residues long and has a mass of 42,742 daltons. However, there are up to 2 reported isoforms. It is a member of the Serpin family, Ov-serpin subfamily. This protein is reported to have a cytoplasmic and secreted cellular localization. For this target protein, ELISA kits with the following species reactivities are available: human, mouse, rat, bovine, chicken, primate, guinea pig, fish, and other mammalian. This target may also be known as: epididymis luminal protein 57, epididymis secretory protein Li 27, peptidase inhibitor 2, serine (or cysteine) proteinase inhibitor clade B (ovalbumin) member 1, and serpin peptidase inhibitor clade B (ovalbumin) member 1.
