Antigens and Antigen Receptors (lecture notes pages 19-24)
... Antibodies bind to antigens based on the ‘complementarity’ of the epitope on the antigen and the antigen-binding site of the antibody. Complementarity can be thought of as ‘goodness of fit’. The better the fit, the stronger the binding. The strength of the reaction is referred to as the affinity of ...
