Transgenic construct used in a position effect assay. Derived from P{wRW}; a XhoI-SpeI fragment has been deleted (removing the w upstream enhancer region) and has been replaced with a 1.7kb KpnI/SpeI fragment containing scs.
Construct: 0.5kb of scs' sequences.
Full length 1.8kb BamHI-BglII scs insulator.
Construct: 1.8kb of scs sequences.
Full length 1.8kb scs insulator.
1.8kb BamHI-BglII fragment containing scs sequences.
