Bio-Activity Immobilized SARS-Cov-2 Spike RBD(B.1.640.2/IHU), His Tag at 0.5 μg/mL (100 μL/well) on the plate. Dose response curve for Human ACE2, hFc Tag with the EC50 of 41.3 ng/mL determined by ELISA. Purity >95% by SDS-PAGE;> 95% by HPLC Endotoxin < 1 EU/μg of the protein by LAL method. Formulation Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Species SARS-CoV-2 Calculated MW 40 kDa 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.Product information
