Anti-RPB9 antibodies enable researchers to detect and measure the RPB9 antigen in biological samples. This target is a reported synonym of the POLR2I gene, which encodes RNA polymerase II subunit I. This protein is known to function in transcription by RNA polymerase II, among other biological roles. The human version of RPB9 has a canonical amino acid length of 125 residues and a protein mass of 14.5 kilodaltons. It is reported to be localized in the nucleus of cells. This target antigen may also be known as hRPB14.5. Western Blot is a widely used application for the RPB9 antibodies listed below. In addition, ELISA is also a common application.
