Protein Construction: A DNA sequence encoding the NCP-CoV(2019-nCoV) spike protein S1 Subunit was expressed with the Fc region of mouse IgG1 at the C-terminus.
Source: 2019-nCoV
Expression Host: HEK293 Cells
QC Testing
Purity: >85 % as determined by SDS-PAGE
Bio Activity: Measured by its binding ability in a functional ELISA. Immobilized human ACE2 protein (His tag) at 2μg/mL (100μL/well) can bind SARSCoV-2 (2019-nCoV) Spike Protein (S1, mFc Tag), the EC50 of 2019-nCoV Spike Protein (S1, mFc Tag) is 90-240 ng/mL. Bio Activity
Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
Predicted N terminal: Val 16
Molecular Mass: The recombinant NCP-CoV(2019-nCoV) Spike Protein (S1 Subunit, mFc Tag) consists of 904 amino acids and predicts a molecular mass of 101.4 kDa.
Formulation: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. Please contact us for any concerns or special requirements.
Usage Guide
Stability & Storage: Samples are stable for twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃ upon receiving. Recommend to aliquot the protein into smaller quantities for optimal storage.
Avoid repeated freeze-thaw cycles.
Reconstitution: Detailed reconstitution instructions are sent along with the products.
