Anti-GADD45 antibodies enable researchers to detect and measure the GADD45 antigen in biological samples. This target is a reported synonym of the GADD45A gene, which encodes growth arrest and DNA damage inducible alpha. This protein is known to function in the apoptotic pathway and DNA repair, among other biological roles. The human version of GADD45 has a canonical amino acid length of 165 residues and a protein mass of 18.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. Other names for this target antigen include DDIT1 and growth arrest and DNA damage-inducible protein GADD45 alpha. Western Blot is the most common application for the GADD45 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
