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