Transgenic construct used in an enhancer-blocking assay. Contains a ftz-lacZ reporter that includes two ftz enhancers (the UPS and NE elements) fused upstream of an Hsp70 promoter followed by the lacZ open reading frame. A 1.2kb XhoI-NotI fragment corresponding to the minimal Fab-7 boundary element has been inserted in between the NE element and the Hsp70 promoter.
Consists of a 1231bp PstI-ApaI fragment including the Fab-7 insulator.
A 1.2kb XhoI-NotI fragment corresponding to the minimal Fab-7 boundary element.
Construct: 1.2kb Fab-7 DNA fragment that spans nucleotide positions 84,594 to 83,423 within the complete BX-C sequence and contains all three DNaseI hypersensitive sites.
Construct: 0.5kb of scs' sequences.
