The ELISA kits listed below target C5, the symbol for the human gene, complement C5. The protein encoded by C5 has a predicted amino acid length of 1676, a mass of 188.3 kDa, and a secreted subcellular localization. Glycosylation has been reported. Pathologic involvement is reported in Complement component 5 deficiency. C5 may also be known by the following names: C5a, C5D, complement component 5, anaphylatoxin C5a analog, C5a anaphylatoxin, C3 PZP-like alpha-2-macroglobulin domain-containing protein 4, and CPAMD4. Orthologs of the gene, including human, mouse, rat, bovine, chicken, primate, guinea pig, fish, and other mammalian are available targets of several ELISA kits.
