Description

Tm2 intron sequences from +413bp to +768bp are fused upstream of an Hsp70 promoter followed by the lacZ coding region.

Proximal muscle enhancer within the first intron of Tm2 is fused upstream of an Hsp70 promoter followed by the lacZ coding region.

Statement
Reference

In embryonic, larval and adult stages, expressed in all muscles analyzed; level of expression approximately half that produced by larger 'whole intron' fragment.(All larval muscles assayed for β-gal activity except the muscles surrounding the dorsal vessel and the spiracle muscles; larger 'whole intron' fragment fails to drive expression in the muscles of the dorsal vessel.)
