Purity: >85 % as determined by SDS-PAGE.
Endotoxin: <1.0 EU per μg protein as determined by the LAL method.
Activity: Testing in progress.
Protein Construction: A DNA sequence encoding the NCP-CoV(2019-nCoV) spike protein S1 Subunit was expressed with the Fc region of human IgG1 at the C-terminus.
Expressed Host: HEK293 Cells
Predicted N Terminal: Val
Molecule Mass: The recombinant NCP-CoV(2019-nCoV) Spike Protein (S1 Subunit, Fc Tag) consists of 908 amino acids and predicts a molecular mass of 101.7 kDa.
Formulation: 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.
Shipping: Generally, 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.
Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Regulatory/ Restrictions: For research use only.
