Transgenic construct used in an enhancer-blocking assay. A 2.3kb BglII-XhoI fragment from the 5' region of N that contains N-fa-swb-INS sequences has been inserted into P{wRW}, in between the w enhancer and w coding sequences.
Construct: 2.3kb BglII-XhoI fragment from the 5' region of N that contains N-fa-swb-INS sequences.
Construct: 0.5kb of scs' sequences.
