Affinity - strength of binding between a single epitope and paratope ... ... Multiple epitope-paratope interactions are involved, so the factors contributing to avidity are complicated (consider the extreme case of a bacterium with multiple non-identical epitopes interacting with an IgM antibody with ten paratopes)<>

Affinity - strength of binding between a single epitope and paratope ... Scatchard plot is generated by plotting r/[H] vs. r ... The bonus effect is that avidity is a multiple of the affinities of the individual interactants (not a simple sum of their affinities); therefore:

However “avidity” is different from “affinity” as avidity is the sum of total strength of binding of more than one molecules to ligands. The difference between them is that affinity is the binding strength of one molecule site to its ligand, but avidity and affinity are correlated.
