Transgenic construct used in an enhancer-blocking assay. HindIII-BssHII fragment of the N-fa-swb-INS sequence from the 5' region of N has been inserted in 3'-5' orientation into P{wRW}, in between the w enhancer and w coding sequences.
Construct: HindIII-BssHII fragment of the N-fa-swb-INS sequence from the 5' region of N.
Construct: 0.5kb of scs' sequences.
