Abstract

An enhancer has been located in the upstream region of the major immediate early gene of human cytomegalovirus and has been isolated, which enhancer is more active than that from SV40 and has a wide host cell spectrum. Hence, it is suitable for eukaryotic expression systems wherein it can be incorporated upstream or downstream of the structural gene or of the regulation region.
