Gateway destination vector. Contains the Drosophila Synthetic Core Promoter (DSCP) promoter, designed to function with a variety of enhancer sequences, upstream of the GAL4 coding sequence and and Hsp70 3'UTR. A tissue-specific enhancer can be swapped in to this vector to generate a tissue-specific GAL4 expression construct which can then be inserted into the genome using phiC31:int integrase.
