Anti-DFF40 antibodies enable researchers to detect and measure the DFF40 antigen in biological samples. This target is a reported synonym of the DFFB gene, which encodes DNA fragmentation factor subunit beta. This protein is known to function in the apoptotic pathway, among other biological roles. The human version of DFF40 has a canonical amino acid length of 338 residues and a protein mass of 39.1 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include CAD, CPAN, and DFF-40. Western Blot is the most common application for the DFF40 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
