POLR2B Antibody (E-12) is a high quality monoclonal POLR2B antibody (also designated POLR2B antibody) suitable for the detection of the POLR2B protein of mouse, rat and human origin. POLR2B Antibody (E-12) is available as both the non-conjugated anti-POLR2B antibody form, as well as multiple conjugated forms of anti-POLR2B antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. RNA polymerase II (Pol II) is a multi-subunit complex responsible for catalyzing the transcription of DNA into RNA. POLR2B (polymerase (RNA) II (DNA directed) polypeptide B), also known as RPB2 (RNA polymerase II subunit B2), is a 1174 amino acid protein that is the second largest subunit in the Pol II complex. POLR2B, along with the other Pol II subunits, uses the four ribonucleoside triphosphates as substrates to catalyze the transcription of DNA to RNA. Localized to the nucleus, POLR2B is one of at least three subunits that form a structure which is essential in maintaining contact between the active site of Pol II and the DNA template/newly synthesized RNA. In addition to POLR2B, this complex contains the central large cleft; a clamp element that opens and closes the cleft and functions to grab the incoming DNA template.
