UASt regulatory sequences drive expression of the Salo\pac, which encodes a puromycin N-acetyltransferase and confers resistance to puromycin.
chemical resistant | larval stage, with Scer\GAL4Act5C.PU
Addition of puromycin to standard fly food (150 micrograms/ml final concentration) is observed to kill all control larvae but not those expressing Salo\pacUAS.cLa driven by Scer\GAL4Act5C.PU.
