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. SARS Spike S1 Protein (hFc & Avi) is expressed in HEK293 mammalian cells with C-hFc-Avi tag. The predicted molecular weight is 100.6 kDa and the accession number is P59594.

Species | SARS |
Expression Host | HEK293 Cells |
Tag | C-hFc-Avi |
Accession Number | P59594 |
別名 | Spike protein S1, S1 protein, Spike,S1 protein, S glycoprotein Subunit1 |
Construction | Ser14-Arg667 |
Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
分子量 | 100.6 kDa (predicted). Due to glycosylation, the protein migrates to 120-140 kDa based on Tris-Bis PAGE result. |
Endotoxin | < 1 EU/μg by the LAL method. |
Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization. |
Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
Stability & Storage |
It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted proteinsolutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
Shipping |
In general, Lyophilized powders are shipping with blue ice. |
