IMMUNOLOGY

Detailed explanation-1: -Affinity is the strength required for an interaction between a site of antigen binding at an antibody and an antigen epitope.

Detailed explanation-2: -The strength of binding of one Fab on an immunoglobulin to one epitope on an antigen is referred to as. Prozone. A situation in which antibody is in excess as compared to antigen is called. Precipitation.

Detailed explanation-3: -Antibody affinity is defined as strength of the binding interaction between antigen and antibody.

Detailed explanation-4: -Avidity describes the measure of overall or accumulated strength of a protein-protein complex, i.e. The total strength of all the non-covalent interactions between an antibody binding to its ligand/s. It is determined by three parameters: The binding affinity of the complex. The valency of the proteins.
