Description
conjugation-Unconjugated-source-Recombinant SARS-COV-2 Spike S1 (D614G) Protein protein is expressed in HEK293 with His-Avi. It contains the amino acid sequence of Gln14-Arg683.-gene_id–swiss_prot-QHD43416.1-applications-WB, ELISA, HPLC-species-SARS-CoV-2-background-The SARS-CoV-2 spike (S) protein is the target of vaccine design efforts to end the COVID-19 pandemic. Despite a low mutation rate, isolates with the D614G substitution in the S protein appeared early during the pandemic, and are now the dominant form worldwide. Here, we analyze the D614G mutation in the context of a soluble S ectodomain construct.-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.
