Wound tumor virus polypeptide synthesis in productive noncytopathic infection of cultured insect vector cells.

abstract：:A retrovirus vector has been developed that selects for instances in which the provirus integrates in close proximity to cellular promoters. Coding sequences for a selectable marker (histidinol dehydrogenase) were inserted into the 3' long terminal repeat (LTR) of an enhancerless Molony murine leukemia virus. Although...
