Anti-GA2 antibodies enable researchers to detect and measure the GA2 antigen in biological samples. This target is a reported synonym of the ETFA gene, which encodes electron transfer flavoprotein subunit alpha. This protein is known to function in electron transport, among other biological roles. The human version of GA2 has a canonical amino acid length of 333 residues and a protein mass of 35.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. Other names for this target antigen include EMA and EMA. Western Blot is the most common application for the GA2 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
