title: Prokaryotic expression of a large fragment of the most antigenic cytomegalovirus DNA-binding protein (ppUL44) and its reactivity with human antibodies.
abstract: We isolated and characterized from a lambda gt11 expression library clones expressing portions of human cytomegalovirus (HCMV)-p52. This nonstructural viral protein is encoded by UL44 and is known to be one of the best IgM reactive antigens. The reactivity of these clones was studied with human antibody and the gene fragment coding for the most immune-reactive portion of p52 (aa 202-434) was cloned in a prokaryotic expression vector, pROS, which overexpresses the antigen as a fusion protein to a truncated molecule of beta-galactosidase.
