A_Ecoli_RNA_Polymerase_Kit_NT73_102017
Total lysates (15 µg protein) from HeLa (lane 1) and E. coli BL21 (lane 2) cells were resolved by electrophoresis (4-12% Bis-Tris gel), transferred to nitrocellulose, and probed with 1:1000 diluted (1 µg/mL) purified anti-E. coli RNA Polymerase β Prime antibody (clone NT73). Proteins were visualized using an HRP goat anti-mouse-IgG secondary antibody (clone Poly4053, Cat. No. 405306). 1:2000 dilution of Direct-Blot™ HRP anti-β-actin antibody (clone 2F1-1, Cat. No. 643807) was used as a loading control (lower). Lane M: MW ladder.

Description

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.

For additional antigen details, please refer to individual product datasheets.

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.
