This sigma factor is the master transcriptional regµLator 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, regµLation and stress management.

Maciag A., Peano C., Pietrelli A., Egli T., De Bellis G., Landini P. Nucleic Acids Res. 39:5338-5355(2011) Purity:Greater than 90% as determined by SDS-PAGE. Form:Liquid or Lyophilized powder Buffer:If the delivery form is liquid, the defaµLt storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution:We recommend that this vial be briefly centrifµged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20?/-80?. Our defaµLt final concentration of glycerol is 50%. Customers coµLd use it as reference. Storage:The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20?/-80?. The shelf life of lyophilized form is 12 months at -20?/-80?. Notes:Repeated freezing and thawing is not recommended. Store working aliquots at 4? for up to one week.
