8RB13_PURE_RNAPolymerasebeta_102717_updated
Total lysates (15 µg protein) from E. coli BL21 cells were resolved by electrophoresis (4-12% Bis-Tris gel), transferred to nitrocellulose, and probed with 1:100000 diluted (0.005 µg/mL) purified anti-E. coli RNA Polymerase β antibody (clone 8RB13). Proteins were visualized using an HRP goat anti-mouse-IgG secondary antibody (clone Poly4053, Cat. No. 405306). Ponceau S staining (lower) was used as loading control.

Description

RNA polymerase (RNAP or RNApol) is an enzyme that produces primary transcript RNA. The β subunit is the second-largest subunit, and is encoded by the roB gene. RNA polymerase β is a subunit which, along wtih α (rpoC), limits core polymerase expression.
