Immunoglobulin G4 (IgG4) is a member of immunoglobulin G produced and secreted by many effective B cells. After gastric protease cleavage, IgG is divided into two F (ab) fragments, each with an antigen binding site and a highly conserved Fc fragment. The Fc segment has highly conserved N-glycosylation sites. The Fc region of the Ig¦Ã-4 chain contains two constant regions (CH2, CH3) of the IgG4 H chain. The characteristic of IgG4 is its ability to form semi antibody molecules through a process called Fab arm exchange, which can lead to the production of bispecific antibodies. Compared with other IgG, this subclass has less inflammation and plays an important role in immune tolerance and regulation. It is used for research and therapeutic applications, particularly for developing antibodies for autoimmune diseases and cancer treatment.
