|Purity||> 95 % as determined by SDS-PAGE.|
|Endotoxin level||< 1.0 EU per μg protein as determined by the LAL method.|
|Storage||Lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at < -20℃ for 3 months.|
|Shipping||In general, recombinant proteins are provided as lyophilized powder which are shipped with ice bag. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.|
|Formulation||Lyophilized from sterile 20 mM Tris, 500 mM NaCl, 10 % glycerol,pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the printed manual.|
|Reconstitution||Please refer to the printed manual for detailed information.|
