Recombinant Virus SARS-CoV-2 S glycoprotein Protein (HEK293)，Strep & His

SARS-CoV-2 S glycoprotein

The SARS-CoV-2 S glycoprotein is critical in infection, binding to the ACE2 receptor and allowing viral particles to attach to the host cell membrane. Cleavage of S2/S2′ triggers cell membrane fusion or internalization via endocytosis. Spike glycoProtein Protein, SARS-CoV-2 (HEK293, Strep, His) is the recombinant virus-derived Spike glycoProtein, expressed by HEK293, with Strep, His labeled tag.

The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.
