There are a number of ELISA Kits available for the measurement of coagulation factor C homolog (Limulus polyphemus), another term for the human protein, cochlin. Other synonyms may include: coagulation factor C homolog cochlin (Limulus polyphemus), COCH-5B2, COCH5B2, and DFNA9. It is encoded by the COCH gene to yield a protein 550 amino acids in length and 59.5 kDa in size. However, there are up to 2 reported isoforms. Versions of coagulation factor C homolog (Limulus polyphemus) are present in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
