| Buffer | The default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol if the delivery form is liquid. The lyophilization buffer is Tris/PBS-based buffer, 6% Trehalose, pH 8.0 if the delivery form is lyophilized powder. Please contact us if you have any special requirment. |
| Reconstitution | Please reconstitute protein in deionized sterile water and we recommend that briefly centrifuge thevial prior to opening the vial .We recommend aliquot for long-term storage at -20℃/-80℃. |
Background
| Relevance | Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of expression of heat shock genes. Intracellular concentration of free RpoH protein increases in response to heat shock, which causes association with RNA polymerase and initiation of transcription of heat shock genes, including numerous global transcriptional regulators and genes involved in maintaining membrane functionality and homeostasis. RpoH is then quickly degraded, leading to a decrease in the rate of synthesis of heat shock proteins and shut-off of the heat shock response. |
