Sequential antigen panning for selection of broadly cross-reactive HIV-1-neutralizing human monoclonal antibodies

Methods Mol Biol. 2009:562:143-54. doi: 10.1007/978-1-60327-302-2_11.

Abstract

Many phage display techniques drive selection toward the isolation of highly specific antibodies. However, the identification of monoclonal antibodies that are cross-reactive has implications for the development of diagnostics, therapeutics, and vaccines against pathogens or cancer cells that are able to rapidly generate variants and escape mutants. To identify human monoclonal antibodies with high activity against HIV and broad-spectrum activity, we developed a technique termed sequential antigen panning. This methodology could be used to isolated recombinant antibodies against any antigen that shares epitopes with other antigens.
