Bat coronavirus Spike Trimer Protein (K978P, V979P), His Tag&Twin-Strep Tag (MALS verified)

DESCRIPTION

The 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 the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
