| Target | Spike S1 |
| Host | SARS-COV-2 |
| Purity | > 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC |
| 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 75.92 kDa. Due to glycosylation, the protein migrates to 90-120 kDa based on Bis-Tris PAGE result. |
| Sl Sequence | Gln14-Arg683(T19R, G142D, E156G, HR157-158 del, L452R, T478K, D614G, P681R) |
| 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 1 EU per μg by the LAL method. |
| Expression System | HEK293 |
| Gene Id | QHD43416.1 |
| Amino Acid Sequence | Recombinant SARS-CoV-2 Spike S1 (Delta B.1.617.2) Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gln14-Arg683(T19R, G142D, E156G, HR157-158 del, L452R, T478K, D614G, P681R). |
