| Form | Liquid or Lyophilization |
| 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 | Guanine nucleotide exchange factor that specifically activates the small GTPase SAR1B. Mediates the recruitment of SAR1B and other COPII coat components to endoplasmic reticulum membranes and is therefore required for the formation of COPII transport vesicles from the ER. Was first identified based on its probable role in the regulation of pituitary gene transcription. Binds to the prolactin gene (PRL) promoter and seems to activate transcription. |
