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.

Immunoglobulin M, or IgM for short, is a basic antibody that is produced by B cells.IgM is by far the physically largest antibody in the human circulatory system. It is the first antibody to appear in response to initial exposure to an antigen.The spleen, where plasmablasts responsible for antibody production reside, is the major site of specific IgM production.gM forms polymers where multiple immunoglobulins are covalently linked together with disulfide bonds, mostly as a pentamer but also as a hexamer. IgM has a molecular mass of approximately 970 kDa (in its pentamer form). Because each monomer has two antigen binding sites, a pentameric IgM has 10 binding sites.
