  • Patent number: 5627058
    Abstract: Retroviruses are used as genetic tools to isolate transcriptionally active chromosomal regions. The retroviruses have a promoterless protein coding sequence located in U3 or U5. The retroviruses may be used to infect cells under conditions which permit selection for instances when the retrovirus integrates in close proximity to and under the control of a cellular promoter. The promoter and its associated gene then may be identified and isolated. In this manner, the retroviruses function as promoter-traps. Related methods and products including vectors, kits and assays are provided.
