2G10_PURE_Sigma-70_Antibody_072219
Whole cell extracts (15 µg protein) from BL21 E. coli cells were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 1.0 µg/mL (1:500 dilution) of purified anti-E. coli RNA Sigma 70 antibody, clone 2G10, overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP Goat anti-mouse IgG antibody (Cat. No. 405306) at a 1:3000 dilution.

Description

RNA polymerase transcribes DNA to synthesize RNA. Prokaryotes contain a single RNA polymerase- core RNA polymerase. RNA polymerase sigma 70 (also known as RNA pol sigma 70 and rpoD) is a part of a family of sigma factor subunits that are required for specific promoter recognition and initiation. RNA pol sigma 70 is the major housekeeping sigma factor responsible for RNA polymerase recognition out of the majority of promoters necessary to transcribe bacterial genes which are expressed during expansion.
