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.
