DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. α subunit plays an important role in subunit assembly since its dimerization is the first step in the sequential assembly of subunits to form the holoenzyme. The β subunit is the second-largest subunit, and is encoded by the rpoB gene. The β’ (β prime) subunit contains structures crucial for transcription, including the sites for ribonucleotide addition and catalysis.

- Recommended Usage
Each lot of antibodies in this kit is quality control tested by Western Blotting. For Western blotting, the suggested uses of these reagents are as follows:
Anti-E. coli RNA Polymerase β Prime (clone NT73): 1:1000-1:4000 (0.25-1ug/mL)
Anti-E. coli RNA Polymerase β (clone NT63): 1:2500-1:100000 (0.005-0.2ug/mL)
Anti-E. coli RNA Polymerase α (clone 4RA2): 1:500-1:5000 (0.1-1.0 ug/mL)
Anti-E. coli RNA Polymerase β (clone 8RB13): 1:2500-1:100000 (0.005-0.2ug/mL)
It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
For verified or reported applications for these antibodies, please see individual product datasheets.
Clone NT73 recognizes epitope 1295-1417 (SLAELLNAGLGGS), and is extremely useful for purifying holoenzymes from enterics. It does not cross-react with mycobacterial smegmatis RNAP. This antibody is used for purifying Softag 1 epitope tagged protein expressed in eukaryotic systems.
Clone NT63 recognizes epitope 922-1090 of ß subunit of the E. coli RNA polymerase and can be used in WB analysis.
Clone 8RB13 is extremely useful for detecting (WB) or purifying (IP) core RNAP from a broad range of bacteria.
Clone 4RA2 specifically recognizes a subunit of the E. coli RNA polymerase.
