avidity

[avid′itē]
Etymology: L, avidus, eager
an inexact measure of the binding strength of antibodies to multiple antigenic determinants on natural antigens.

avidity

The degree of stability of an antibody’s binding with its antigen, which is a function of the number of shared binding sites and the binding energy of the antibody and antigen, which is the sum of the binding affinities of the combining sites on the antibody.
