RpoS Protein, E. coli, Recombinant (His)

SKU: orb1979183

Description

Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response. Controls, positively or negatively, the expression of several hundred genes, which are mainly involved in metabolism, transport, regulation and stress management.; Protects stationary phase cells from killing induced by endoribonuclease MazF.

Research Area

,Recombinant-Protein

Images & Validation

• Application Notes:
  Reconstitute the lyophilized protein in sterile deionized water. The product concentration should not be less than 100 μg/mL. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
