Description

conjugation-Unconjugated-source-Recombinant SARS-COV-2 Spike S Trimer (D614G) Protein protein is expressed in HEK293 with His-Avi. It contains the amino acid sequence of Val16-Glu1188 (D614G).-gene_id-QHD43416.1-swiss_prot–applications-WB, ELISA, HPLC-species-SARS-CoV-2-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.-storage_buffer-Lyophilized from 0.22um filtered solution in 20mM PB (pH 7.4). 5% trehalose is added as a protectant before lyophilization.-storage_condition-The product should be stored at -70°C or -20°C.-expression_system-HEK293-tag-His-Avi-purity-> 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC-endotoxin-Less than 1EU per ug by the LAL method.
