Medical Definition of IgM

1. An immunoglobulin M molecule (970 kD) is built up from five immunoglobulin G type monomers joined together, with the assistance of J chains, to form a cyclic pentamer. Immunoglobulin M binds complement and a single molecule bound to a cell surface can lyse that cell. Immunoglobulin M is usually produced first in an immune response before immunoglobulin G. The human red cell isoantibodies are immunoglobulin M antibodies. Heavy chain (mu chain) is rather larger than the heavy chains of other immunoglobulins. (30 Mar 1998)
