Abstract
Understanding the epitopes of antibodies elicited by infection and vaccination is often useful in immunogen design. In this chapter, we describe biolayer interferometry (BLI)-based methods to evaluate such epitopes and permit simultaneous analysis of antibodies from several sources, including monoclonal antibodies (mAbs) and polyclonal serum antibodies (pAbs). Using previously characterized antibodies with known epitopes as controls, the distribution of epitopes for the influenza hemagglutinin (HA) is shown for isolated human mAbs and pooled serum from HA-immunized mice. This method is versatile, high-throughput, and can be adapted to several antigens.
