Abstract

IgM and IgG are the only classes of immunoglobulin capable of initiating the classical complement cascade. IgM, however, fixes complement much more effectively than IgG making it a more attractive Fc for some immunotherapeutic strategies. IgG, on the other hand, triggers additional effector functions mediated through gamma specific Fc receptors. Using a generalizable technique we have produced IgM-like polymers of IgG that possess both the Fc gamma receptor binding properties of IgG and the more potent complement activity of IgM.
