Description and Uses
Description

Transgenic construct used to study the impact of interactions between su(Hw) insulators on transvection. Contains 1. a loxP cassette that contains four su(Hw) protein binding sites, 2. an FRT cassette that contains the w eye enhancer, 3. the y transcription unit (including the bristle enhancer), and 4. four su(Hw) protein binding sites.
