Abstract: Substantially-pure immunogenic glycoprotein complexes of the gCII family, and constituent glycoproteins which can be derived from the membrane envelope of human cytomegalovirus are provided.
Abstract: The present invention is directed to a composition containing a first monoclonal antibody, capable of neutralizing human cytomegalovirus (HCMV), that binds to a first epitope on HCMV GCA, and a second non-neutralizing HCMV monoclonal antibody that binds to a second epitope on HCMV GCA. The GCA complex includes antigenically-related glycoproteins of molecular weights 130,000, 93,000, and 50,000-52,000 kDa. The mixture of the two antibodies has greater neutralizing activity than a composition containing the first antibody alone. Also provided is a method for neutralizing the infectivity of HCMV using the composition.
