< 1.0 EU per μg protein as determined by the LAL method.
Testing in progress
A DNA sequence encoding the cynomolgus IL31 (EHH66805.1) (Met1-Thr163) was expressed with a polyhistidine tag at the C-terminus.
The recombinant cynomolgus IL31 consists of 148 amino acids and predicts a molecular mass of 16.8 kDa.
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 hard copy of CoA.
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.
安定性 & 保存条件
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.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
