Anti-CRISP1 antibodies are used in the immunodetection of the protein cysteine rich secretory protein 1. In humans, the canonical protein has a reported length of 249 amino acid residues and a mass of 28.5 kDa. Its subcellular localization is in the mitochondria. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the epididymis. A member of the CRISP protein family, CRISP1 is suspected to have a role in sperm-egg fusion and maturation. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include AEGL1 and ARP. CRISP1 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some CRISP1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
