Provided below are ELISA kits targeting chordin like 1, a human protein encoded by CHRDL1. This protein is 456 amino acids long with a reported mass of 52 kDa. 4 isoforms have been identified. This is reported to be a secreted protein. There is a noted implication in Megalocornea 1, X-linked. Other alias names for this protein include: chordin-like protein 1, neuralin-1, neurogenesin-1, ventroptin, MGCN, NRLN1, and VOPT. ELISA kits are available that are reactive to human, mouse, rat, bovine, chicken, primate, guinea pig, and other mammalian variants of the target antigen.
