IgG is the most abundant antibody in the human body, constituting about 75% of the total. It plays a crucial role in fighting infections by coating various microorganisms, preventing them from entering the body.

IgM is another type of antibody found in blood plasma, representing 5-10% of the total. It is a large antibody molecule, five times bigger than IgG, and is produced by plasma cells.

IgA is present in various bodily fluids like tears, saliva, digestive juices, respiratory fluids, blood, and lymph. It acts as a barrier, preventing microorganisms from entering the body.

IgE is involved in allergic reactions and parasitic infections. It binds to mast cells and basophils, triggering the release of histamine and other inflammatory mediators.

IgD is an antibody present on the surface of B cells. It plays a crucial role in B cell activation and differentiation.

IgD is present on the surface of B cells, contributing to their activation and differentiation. This process leads to the production of other antibodies, like IgG and IgM, which play a more direct role in fighting infections.

IgD found on the surface of B cells acts as a receptor for antigens, triggering the activation of these cells. This activation results in the production of antibodies that can neutralize pathogens and contribute to immunity.
