Source DNA sequence encoding extracellular fragment[16-1220] of COV2 Spike S protein(S1+S2) [accession# QIC53204.1] variant (B.1.1.529/Omicron) (A67V, del69-70, T95I, del142-144, Y145D, del211, L212I, ins214EPE, G339D, S371L, S373P, S375F, K417N, N440K, G446S, S477N, T478K, E484A, Q493R, G496S, Q498R, N501Y, Y505H, T547K, D614G, H655Y, N679K, P681H, N764K, D796Y, N856K, Q954H, N969K, L981F)including a C terminal His AVI tag was expressed in HEK cells.
Biotinylation The COV2 Spike is then biotinylated in vitro at a single site using the AVItagTM biotinylation technology.
Molecular weight Recombinant COV2 Spike protein B.1.1.529 encodes the NCOV spike glycoprotein S1+S2 sequences . Recombinant COV2 Spike migrates due to glycosylation as an approximately 130 kDa protein under reducing conditions in SDS-PAGE.
Activity To be tested
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 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.
