Product Description	Recombinant SARS-COV-2 Spike S Trimer(D614G) Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Val16-Glu1188 (D614G).
Product Background	The SARS-CoV-2 spike (S) protein variant D614G supplanted the ancestral virus worldwide, reaching near fixation in a matter of months. Recently, that D614G was been found more infectious than the ancestral form on human lung cells, colon cells, and on cells rendered permissive by ectopic expression of human ACE2 or of ACE2 orthologs from various mammals, including Chinese rufous horseshoe bat and Malayan pangolin.
Product Category	Recombinant Protein / Antibody discovery
