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. This product is the recombinant human SARS-CoV-2 RBD protein expressed from human 293 cells (HEK293).
