Abstract
A bacteriophage which is characterized by the presence of one or more restriction enzyme sites downstream from the late promoter up to the cohesive end, and none or a permissible number of restriction enzyme sites upstream from the late promoter to the cohesive end is useful as an expression vector. The vector can be used to obtain high expression of DNA inserted at the restriction enzyme site downstream from the late promoter up to the cohesive end.
