Transgenic construct used to study insulator function. Contains divergently transcribed w and lacZ reporters. The h H1 enhancer and the Abd-B IAB5 enhancer have been inserted between the two reporters (IAB5 is proximal to lacZ). A 590bp BamHI minimal Fab-8 fragment has been inserted in between the H1 and IAB5 regulatory sequences.
Construct: 590bp BamHI minimal Fab-8 fragment.
