| Product name | Recombinant SARS-CoV-2 Spike S1(D614G) Protein |
|---|---|
| Catalog No. | RP01287 |
| Description | Recombinant SARS-CoV-2 Spike S1(D614G) Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Val16-Arg685(Asp614Gly)) of sars-cov-2 Spike S1(D614G) (Accession #QHD43416.1) fused with a 6×His tag at the C-terminus. |
| Bio-Activity | Measured by its binding ability in a functional ELISA. Immobilized recombinant SARS-CoV-2 Spike S1 at 2 μg/mL (100 μL/well) can bind recombinant Human ACE2 with a linear range of 0.03-6.26 ng/mL. |
| Purity | > 95% by SDS-PAGE. |
| Endotoxin | < 1.0 EU/μg of the protein by LAL method. |
| Formulation | Supplied as a 0.22 μm filtered solution in PBS, pH 7.4 or Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. |
| Species | SARS-CoV-2 |
| Calculated MW | 75.79 kDa |

| Storage | Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week. |
|---|---|
| Reconstitution | Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles. |
