Affinity between individual antigen and antibody molecules depends on several types of bonds,such as ionic bonds,hydrophobic bonds,hydrogen bonds,and van der Waals forces.How is the strength of these attractions characterized?

Question

Quizplus · Accepted Answer

The strength of the attractions between antigen and antibody molecules is characterized by avidity, which refers to the overall strength of binding due to multiple interactions between different binding sites. Specificity refers to the ability of an antibody to bind to a particular antigen, reactivity refers to the ability of an antigen-antibody complex to induce a biological response, and multivalency refers to the ability of an antigen or antibody to have multiple binding sites.
