Different classes of immunoglobulins are distinguished by the structure of their heavy chain constant regions. IgM is the first antibody isotype secreted following activation of a naive B cell. IgM is found at high concentrations in the serum, and is found as a very high molecular weight complex. This high molecular weight complex is composed of: A single IgM monomer plus monomers of IgA and IgG A single IgM monomer bound to several non-immunoglobulin serum proteins A single IgM monomer bound to serum complement components A pentamer of IgM monomers Two dimers of IgM plus IgD forming a tetrameric complex
