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