Immunoglobulin Variants
IgG, IgM, IgA, IgE, IgD; genetic determinants that vary among individuals.
Primary antibody response
The immune response that occurs upon the first exposure to an antigen.
Secondary antibody response
An enhanced immune response upon repeated exposure to the same antigen.
Antibody affinity
The individual strength of binding between an antibody and its antigen.
Antibody avidity
Overall strength of binding, influenced by multiple binding sites.
Immune complexes
Noncovalent combinations of antibodies and antigens.
Opsonin effect
The process by which proteins bind to foreign particles, enhancing phagocytosis.
Types of bonding in antigen-antibody interactions
Includes hydrophobic bonding, hydrogen bonds, van der Waals forces, and electrostatic forces.
Goodness of fit
The compatibility between an antibody-combining site and an antigen determinant.
Monoclonal antibodies
Antibodies produced by identical immune cells that are clones of a unique parent cell.
