Binding Antibody. Antigen binding is the primary function of the Fab region of IgG. The apposition of the three-strand faces of the V regions of the L and H chains leaves a cavity between them into which small molecules may fit, and the surface display of the hypervariable regions of the combined V regions forms a surface at the end of the Fab fragment which may bind in a noncovalent fashion ...

Receptor/ligand binding affinity. The interaction of most ligands with their binding sites can be characterized in terms of a binding affinity. In general, high-affinity ligand binding results from greater intermolecular force between the ligand and its receptor while low-affinity ligand binding involves less intermolecular force between the ligand and its receptor.
