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. |
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. |
