Measured in antiviral assays using WISH human amnion cells infected with vesicular stomatitis virus(VSV).
The EC50 for this effect is typically 0.6-4.2pg/mL.
A DNA sequence encoding the human IFNA2 (NP_000596.2) (Cys24-Glu188) was expressed.
Predicted N Terminal
The recombinant human IFNA2 consists 165 amino acids and predicts a molecular mass of 19.3 kDa.
Lyophilized from sterile PBS, pH 7.4.
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us
for any concerns or special requirements.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.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -70℃
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.
