$1,200.00 – $2,500.00
| accession | NCOVS1 |
| Source | DNA sequence encoding the COVID-19 Spike extracellular fragment[16-675] of NCOV Spike S1 [accession# QIC53204.1] including a C-terminal His tag was expressed in CHO Cells. |
| Molecular weight | Recombinant 2019-nCoV Spike S1 is a protein consisting of 680 amino acid residues ,due to glycosylation migrates as an approximately 80 kDa protein on SDS-PAGE. |
| Purity | >95%, as determined by SDS-PAGE and HPLC |
| 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). |
| Presentation | Recombinant COVID-19 Spike S1 was lyophilized from 0.2 µm filtered PBS solution pH7.4 |
| Reconstitution | A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers. |
| Storage | The lyophilized protein is stable for at least 2 years from date of receipt at -20° C. |
