Anti-RFN antibodies enable researchers to detect and measure the RFN antigen in biological samples. This target is a reported synonym of the REXO2 gene, which encodes RNA exonuclease 2. This protein is known to function in metabolic processes, among other biological roles. The human version of RFN has a canonical amino acid length of 237 residues and a protein mass of 26.8 kilodaltons. It is reported to be localized in the nucleus, mitochondria, and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include CGI-114 and REX2. Western Blot is the most common application for the RFN antibodies listed below. ELISA and Immunohistochemistry are also common applications.
