$350.00 – $1,200.00
accession | NCOVS |
Source | DNA sequence encoding the COVID-19 Spike S protein extracellular domain,[14-1211] accession #QHD43416.1 including a C-terminal Fc AVI tag was expressed in HEK Cells. (The furin protease cleavage site was mutated at position 683) |
Molecular weight | Recombinant 2019-nCoV Spike S protein is a protein consisting of the S1+S2 subunits with a calculated MW of 160kDa ,due to glycosylation migrates as an approximately 220 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 nCoV-2019 Spike S protein was lyophilized from 0.2 µm filtered PBS pH 7.4 |
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. |
Usage | This product is for research purposes only.It may not be used for therapeutics or diagnostic purposes. |
