The ELISA kits listed below target COL1A1, the symbol for the human gene, collagen type I alpha 1 chain, and a member of the Fibrillar collagen family. The protein encoded by COL1A1 has a predicted amino acid length of 1464, a mass of 138.9 kDa, and a secreted subcellular localization. Glycosylation has been reported. Pathologic involvement is reported in Caffey disease. COL1A1 may also be known by the following names: pro-alpha-1 collagen type 1, collagen type I alpha 1, collagen alpha-1(I) chain preproprotein, collagen alpha 1 chain type I, alpha1(I) procollagen, and alpha-1 type I collagen, and type I procollagen alpha 1 chain. Orthologs of the gene, including human, mouse, rat, bovine, chicken, primate, guinea pig, fish, and other mammalian are available targets of several ELISA kits.
