Anti-C53 antibodies enable researchers to detect and measure the C53 antigen in biological samples. This target is a reported synonym of the POLR3D gene, which encodes RNA polymerase III subunit D. This protein is known to function in innate immune responses, among other biological roles. The human version of C53 has a canonical amino acid length of 398 residues and a protein mass of 44.4 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include BN51T and RPC4. Western Blot is the most common application for the C53 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
