Protocol to identify and monitor key mutations of broadly neutralizing antibody lineages following sequential immunization of Ig-humanized mice.

Abstract excerpt

Using the VRC01-class of anti-HIV-1 broadly neutralizing antibodies (bnAbs) elicited in sequentially immunized Ig-humanized mice as an example, we describe a protocol to identify key mutations for bnAb function by point mutagenesis and antibody binding and neutralization assays. We also describe steps to monitor how the key mutations arise in response to specific immunogens, which is critical for vaccine...
