Structure: IgM is a 900 kDa pentavalent protein. The molecule possesses five variable regions each composed of light and heavy chains. IgM is the first immunoglobulin produced upon antigenic stimulation. The variable region imparts unique binding specificity while the heavy chain Fcµ constant region provides functional characteristics of the isotypic class.

Production: Plasma cells synthesizes IgM after antigenic stimulation. The IgM synthesized will recognize and bind to the specific stimulating antigen.
