Sf21 insect cell expressed, over 95% purity  

SARS-CoV-2, which causes the global pandemic coronavirus disease 2019 (Covid-19), belongs to a family of viruses known as coronaviruses that are commonly comprised of four structural proteins. One of the proteins, SARS-CoV-2 Spike Protein (S Protein), is a glycoprotein that mediates membrane fusion and viral entry, and as such is a crucial COVID-19 target.  R&D Systems SARS-CoV-2 Spike range of bioactive proteins are valida…
