SARS Spike RBD Protein (His & Avi)
(Synonyms: Spike protein RBD, S protein RBD, S glycoprotein RBD) Copy Product InfoSynonyms: Spike protein RBD, S protein RBD, S glycoprotein RBD
Catalog No. TMPK-00911 Copy Product Info
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 RBD Protein (His & Avi) is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 27.9 kDa and the accession number is P59594.

| Species | SARS |
| Expression System | HEK293 Cells |
| Tag | C-His-Avi |
| Accession Number | P59594 |
| Construction | Arg306-Phe527 |
| Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
| Endotoxin | < 1.0 EU/μg of the protein as determined 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°C. For reconstituted protein solutions, 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 shipped with blue ice, while solutions are shipped with dry ice. |
| Synonyms | Spike protein RBD, S protein RBD, S glycoprotein RBD |
| Research Background |
| Molecular Weight | 27.9 kDa (predicted). Due to glycosylation, the protein migrates to 36-46 kDa based on Tris-Bis PAGE result. |
| Storage | Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months |
