NT63_PURE_RNA_PolymeraseBeta_WB_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 NT63). 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.

    Total cell lysate from E Coli. Strain BL21 (15 µg protein) was resolved by 4-12% Bis-Tris gel electrophoresis, transferred to nitrocellulose, and probed with 0.1 µg/mL (lane 1), 0.05 µg/mL (lane 2), 0.025 µg/mL (lane 3), 0.0125 µg/mL (lane 4) and 0.00625 µg/mL (lane 5) of Purified anti-E. coli RNA Polymerase β Antibody (clone NT63) (upper blot). Proteins were visualized using chemiluminescence detection after incubation with a 1:3000 dilution of HRP conjugated anti-mouse-IgG secondary antibody for anti-E. coli RNA Polymerase β Antibody (upper blot). Ponceau S staining (lower blot) was used as loading control. Lane M: Molecular Weight Marker

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 rpoB gene. RNA polymerase β is a subunit which, along with α (rpoC), limits core polymerase expression.
