Anti-SARS-80R mAb（Cat No.:I044222）is a human monoclonal antibody that targets the receptor-binding domain (RBD) of the SARS-CoV spike (S) protein. It binds with high affinity to the ACE2 binding site, effectively neutralizing the virus by preventing its attachment and entry into host cells. Isolated from a non-immune human antibody library, 80R demonstrates potent antiviral activity against SARS-CoV and has been instrumental in structural and functional studies of coronavirus spike proteins. It serves as a model therapeutic antibody in the development of treatments for SARS and related viral infections.
