Anti-FAPA antibodies enable researchers to detect and measure the FAPA antigen in biological samples. This target is a reported synonym of the FAP gene, which encodes fibroblast activation protein alpha. This protein is known to function in angiogenesis and cell adhesion, among other biological roles. The human version of FAPA has a canonical amino acid length of 760 residues and a protein mass of 87.7 kilodaltons, although 2 isoforms have been identified. This target antigen may also be known as DPPIV. Immunohistochemistry is the most common application for the FAPA antibodies listed below. ELISA and Western Blot are also common applications.
