Anti-CCA antibodies enable researchers to detect and measure the CCA antigen in biological samples. This target is a reported synonym of the FBN2 gene, which encodes fibrillin 2. This protein is known to function in eye development and carbohydrate metabolism and homeostasis, among other biological roles. The human version of CCA has a canonical amino acid length of 2912 residues and a protein mass of 314.8 kilodaltons, although 2 isoforms have been identified. It is reported to be a secreted protein that is notably expressed in the placenta. This target antigen may also be known as DA9. ELISA is a widely used application for the CCA antibodies listed below. In addition, Western Blot is also a common application.
