Chapter 6 Ag-Ab Interactions

Chapter 6 Ag-Ab Interactions. Nature of the Ag-Ab interaction Immunological assays. 4 types of noncovalent forces. Affinity The strength of the total noncovalent interactions between a single Ag-binding site on an Ab and a single epitope is the affinity of the Ab for that epitope.
