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.

蛋白构建 | 1-330 aa |
蛋白纯度 | > 85% as determined by SDS-PAGE. |
分子量 | 38.1 kDa as predicted |
缓冲液 | If the delivery form is liquid, the default 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. |
复溶方法 | A hardcopy of COA with reconstitution instructions is sent along with the products. Please refer to it for detailed information. |
存储 |
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C. |
运输方式 |
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. |
