Description and Uses
Description

Transgenic construct that is designed to test for chromosomal position effects (CPE) when inserted in the genome. It comprises 3'-to-5': an attR site, an FRT cassette containing the M2 insulator (a dimer of the 215bp M fragment from the scs' insulator, including the high affinity BEAF-32 protein binding site), a w+mC minigene, a 990bp scs insulator, an attL site, and a loxP cassette containing the y+mDint2 marker. The M2 insulator can be excised using FLP recombinase to test for CPE at a particular genome insertion site, allowing insertion sites with the desired CPE properties to be identified. The sequence between the attL and attR site can then be excised using phiC31:Dint(KEE) disintegrase, regenerating a functional attP 'landing' site that is marked with a loxP cassette containing y+mDint2.
