I have used supF as a tool to examine retroviral integration in vitro.
These studies involved integrating a small linear DNA (supF flanked
by 15 nt of viral U3 and U5 sequences) into pBCSK+, a plasmid from
Integrants were detected by transformation into MC1061/P3. In
this system, selection with [Amp - 30, Tet - 7.5, Kan - 10] (all
values in micrograms/ml final) resulted in selecting for integrants
in one orientation.
Dropping the selection to [Amp - 20, Tet - 5.0, Kan - 10] resulted
in detecting integrants in both orientations.
The results and our interpretation of them were published as
J. Virol. 70: 3571-3580 (June 1996).
