These RPB9 ELISA kits are immunodetection tools for measuring the levels of RPB9 in biological samples. RPB9 is an alias of the human POLR2I gene, which encodes the protein, RNA polymerase II subunit I. Notably, RPB9 is known to play a role in transcription by RNA polymerase II, among other functions. The POLR2I protein is described to be 125 amino acid residues in length and 14.5 kilodaltons in mass. It is localized to the nucleus of the cell. Other names for this target antigen include hRPB14.5.
