The development of antibodies for either detection or therapeutics requires extensive characterization of several potential leads. One of the critical steps in the characterization process is epitope mapping (binning), where the different antibodies are divided into "bins" according to their antigen recognition site, which is directly linked to their functional activity. Biolayer interferometry (BLI) is a technology used to characterize interactions between macromolecules and, as such, is used extensively to characterize antibodies. The current protocol describes the use of BLI for antibody binning. Along the classical pairwise mapping model, this protocol addresses the challenges of binning on multivalent antigens as well as characterizing non-purified antibodies.

Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
