| Host: | HEK293 |
| Note: | STRICTLY FOR FURTHER RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS. |
| Short Description : | Recombinant-2019 nCoV/COVID19 Spike protein S-protein was developed from hek293. For use in research applications. |
| Conjugation: | Unconjugated |
| Formulation: | Lyophilised from 0.2 µm filtered 20 mM Tris, 300 mM NaCl, 10 % glycerol, pH 8.0. |
| Dilution Range: | Spin the vial and reconstite in distilled water to a concentration not less than 0.1 mg/mL. This can then be diluted into other buffers. |
| Storage Instruction: | The lyophilized protein is stable for at least 1 year from date of receipt at-20°C. NA |
| Endotoxin: | Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg (1EU/µg). NA |
| Immunoreactivity: | The activity was tested by binding Human ACE2 in functional ELISA assay. NA |
| Immunogen Region: | ECD |
| Immunogen: | DNA sequence encoding the COVID-19 Spike S protein extracellular domain, [16-1220] accession #QIC53204.1 including a C-terminal His tag was expressed in HEK Cells. NA |
| Background | Recombinant 2019-nCoV Spike S protein is a protein consisting of the S1+S2 subunits contains 1210 amino acid residues, due to glycosylation migrates as an approximately 120 kDa protein on SDS-PAGE. |
