Note
pChs-Gal4 is a P-element vector that allows the direct insertion of identified enhancer fragments in front of a Gal4 sequence without the need for its own promoter sequences. The vector pChs-Gal4 is a derivative of pCaSpeR-hs43-AUG-lacZ (Thummel and Pirrotta, 1992) and pGaTB (Brand and Perrimon, 1993).
