Recombinant 2019-nCOV Spike Protein (S2 ECD) was produced in Baculovirus-Insect Cells and fused with a His tag at the C-terminus.
S protein S2; 2019-nCoV S2 protein; SARS-COV2 S2 protein; COVID-19 spike S2 protein
The recombinant 2019-nCoV Spike Protein (S2 ECD, His tag) consists of 539 a.a and predicts a molecular weight of 59.37 kDa.
<1.0 EU per μg protein as determined by the LAL method.
> 90 % as determined by SDS-PAGE.
Lyophilized from sterile 20 mM PB, 300 mM NaCl, 10 % glycerol, pH 7.0.
Store the 2019-nCoV Spike Protein S2 under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
