Abstract

Immunogold electron microscopy has demonstrated that human immunoglobulin G (IgG) can bind to the tegument of human cytomegalovirus virions by the Fc portion of the molecule. This binding was inhibited by preincubation of the Fc probes with protein A. Treatment of AD169 virions with Triton X-100 allowed release of the Fc-binding proteins, which were precipitated and characterized by polyacrylamide gel electrophoresis (PAGE). Polypeptides of approximately 69 and 33 kDa were recovered and shown by immunoblotting to retain their capacity to bind Fc-gold after separation under both reducing and nonreducing conditions. The combined results of blocking experiments, PAGE of precipitates, and Western blots (immunoblots) indicate that the tegument proteins which bind IgG-Fc are identical to those which bind beta 2 microglobulin.
