Description

conjugation-Unconjugated-source-SARS-COV-2 Spike RBD Protein protein is expressed in HEK293 with hFc. It contains the amino acid sequence of Arg319 – Phe541.-gene_id-QHD43416.1-swiss_prot–applications-WB, ELISA, HPLC-species-SARS-CoV-2-background-The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting 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-hFc-purity-> 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC-endotoxin-Less than 1EU per ug by the LAL method.
