Antibody Escape

We determined the effects of receptor binding protein mutations on antibody neutralization. Antibody selections were performed by incubating pseudovirus libraries with different concentrations of antibody, followed by infection of CHO cells expressing bat ephrin-B3. Neutralization curves were fit on the DMS data with polyclonal.

In total, we measured the effects of receptor binding protein mutations for six different antibodies that target three different epitopes.

Antibody Escape Validations

To validate the escape measurements from DMS, we generated single RBP mutant pseudoviruses and tested their neutralization by antibody nAH1.3.
