• 
  Western blot analysis of POLR2B expression in SHSY5Y (A), HepG2 (B), mouse brain (C), rat ovary (D) whole cell lysates. (Predicted band size: 133 kD; Observed band size: 134 kD)
• 
  Immunohistochemical analysis of POLR2B staining in rat liver formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
