Description

conjugation-Unconjugated-source-Recombinant SARS-CoV-2 Spike S1 protein is expressed in HEK293 with His-Avi. It contains the amino acid sequence of Gln 14-Arg 683.-gene_id–swiss_prot-QHD43416.1 -applications-WB, ELISA, HPLC-species-SARS-CoV-2-background-The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensinconverting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.-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.
