Recombinant SARS-CoV Spike RBD Protein (Catalog # 40150-V08B2)


It is a chimeric monoclonal antibody that combines the constant domains of the human IgG1 molecule with mouse variable regions. The variable region was obtained from a mouse immunized with purified recombinant SARS-CoV peak RBD protein. The antibody was produced using recombinant antibody technology.

Microneutralization (MN):

Neutralization activity is measured by an in vitro microneutralization assay. The virus microneutralization (MN) test was performed on 293T-ACE2 cells infected with the SARS-CoV-2 Spike pseudovirus (2019-nCoV) under treatment with serial dilutions of neutralizing antibody. The infection was neutralized by increasing concentrations of Anti-SARS-CoV-2 Neutralizing Antibody (Catalog # 40150-D001). The inhibition rate was determined by comparing the relative light unit (RLU) of the luciferase reporter at different antibody concentrations. The IC50 is typically 46.762 µg / ml.
