Storage and Stability :
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Endotoxin Level :
< 1.0 EU per μg of the protein as determined by the LAL method

Protein Construction :
A DNA sequence encoding the HIV-1 envelope glycoprotein gp160 extracellular domain (Val30-Tyr677), termed as gp140, was fused with the bacteriophage T4 fibritin and a polyhistidine tag at the C-terminus.

Buffer Solution :
Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hardcopy of datasheet.

Shipping :
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.

Redissolution :
A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
