| Scientific Background | The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity. |
| Molecular Mass | The protein has a predicted MW of 35 kDa. Due to glycosylation, the protein migrates to 55-70 kDa based on Bis-Tris PAGE result. |
| Sl Sequence | Val16-Ser305 |
| Solubility | Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 μg or less, at 1mg/ml for 500μg or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking. |
| Appearance | Lyophilized |
| Endotoxin Levels | Less than 0.01 EU per μg by the LAL method. |
| Expression System | HEK293 |
| Gene Id | QHD43416.1 |
| Amino Acid Sequence | Recombinant SARS-COV-2 Spike S1 NTD Protein is expressed from HEK293 with His tag and Flag tag at the C-Terminus.It contains Val16-Ser305. |
| Storage | -20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. |
