Sars-cov-2 (2019-NCOV) infects human respiratory epithelial cells through binding to human ACE2 receptors. Spike protein is a large type I transmembrane protein containing two subunits S1 and S2.S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing cell surface receptors. S2 contains the basic elements required for membrane fusion. S protein plays a key role in inducing neutralizing antibody and T cell responses as well as protective immunity.
Immobilized SARS-CoV-2 Omicron RBD (BA.2.75), His tag at 4 μg/mL (50 μL/well) can bind Human ACE2/ACEH Protein with EC50 of 28.35-38.39 ng/mL.
