Anti-POLR2J3 antibodies are used in the immunodetection of the protein RNA polymerase II subunit J3. In humans, the canonical protein has a reported length of 115 amino acid residues and a mass of 13.1 kDa. Its subcellular localization is in the nucleus. It is a member of the Archaeal Rpo11/eukaryotic RPB11/RPC19 RNA polymerase subunit protein family. Synonyms for this target antigen include DNA-directed RNA polymerase II subunit 11, DNA-directed RNA polymerase II subunit J3, RNA polymerase II subunit B11-b2, and DNA-directed RNA polymerase II subunit RPB11-b2. Western Blot is a widely used application for the POLR2J3 antibodies listed below. In addition, Flow Cytometry is also a common application.
