Structure of Monoclonal Antibodies

Immunoglobulins (Ig) or antibodies (Ab) are the key functional units of the humoral immune system. Antibody molecules have a highly specialized structure that can mediate biological response upon specifically binding to an antigen. This chapter introduces readers to the chemical structure of antibodies, with specific focus on the structure of immunoglobulin G (IgG). The chapter also highlights functionally important IgG domains and their susceptibility to chemical degradation.
