Listed are ELISA Kits for the detection of MCM21R, an alias name of centromere protein O. The human protein, encoded by the gene CENPO, is 300 amino acid residues long and has a mass of 33,786 daltons. However, there are up to 2 reported isoforms. It is a member of the CENP-O/MCM21 family. This protein is reported to have a 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: centromeric protein O, interphase centromere complex protein 36, CENP-O, and ICEN-36.
