Anti-VISA antibodies enable researchers to detect and measure the VISA antigen in biological samples. This target is a reported synonym of the MAVS gene, which encodes mitochondrial antiviral signaling protein. This protein is known to function in innate immune responses, among other biological roles. The human version of VISA has a canonical amino acid length of 540 residues and a protein mass of 56.5 kilodaltons, although 6 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. A number of VISA antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
