Immunoglobulins are basically proteins that function as antibodies. The terms antibody and immunoglobulin are often used interchangeably. Immunoglobulins are found in blood and other tissues and fluids. They are made by the plasma cells that are derived from the B cells of the immune system.B cells of the immune system become plasma cells when activated by the binding of a specific antigen on its antibody surfaces.hey are made by the plasma cells that are derived from the B cells of the immune system.

In response to specific antigens, immunoglobulins are formed in the bone marrow, spleen, and all lymphoid tissues except the thymus. Classes of immunoglobulins are IgA, IgD, IgE, IgG, and IgM. Also called immune serum globulin.See also antibody, antigen, immunity.gG is the most abundant of the five classes of immunoglobulins, representing about 80% of serum immunoglobulin protein. It is the major antibody in the secondary humoral response of immunity, serves to activate the complement system, and is frequently involved in opsonization.
