Bioactivity
Chemical Properties
Storage & Solubility Information
| Bioactivity | Activity testing is in progress. It is theoretically active, but we cannot guarantee it. If you require protein activity, we recommend choosing the eukaryotic expression version first. |
| Description | SARS-CoV-2 Spike S1 NTD Protein (His & Avi), Biotinylated is expressed in HEK293 mammalian cells. The predicted molecular weight is 35.89 kDa and the accession number is A0A6G7K2L4. |
| Species | SARS-CoV-2 |
| Expression System | HEK293 Cells |
| Tag | C-His-Avi |
| Accession Number | A0A6G7K2L4 |
| Construction | A DNA sequence encoding the SARS-CoV-2 (2019-nCoV) Spike S1 NTD (YP_009724390.1) (Met1-Ser305) was expressed with a C-terminal polyhistidine tag followed by an AVI tag. The purified protein was biotinylated in vitro. Predicted N terminal: Val16 |
| Protein Purity | > 90 % as determined by SDS-PAGE. |
| 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, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization. |
| Reconstitution | A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information. |
| 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. |
| Research Background |
| Molecular Weight | 35.89 kDa (predicted) |
| Storage | Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months |
