The following information accompanied stocks donated to the Bloomington Drosophila Stock Center by Dawen Cai, University of Michigan, Ann Arbor: PBac{nSyb(FRT13.FLP)} Self-regulating Flippase under the regulation of the n-Synaptobrevin promoter. FLP sequence is flanked by two FRT-F13 sites, corresponding to medium excising probability hence medium FLP activity. P{nSyb(FRT15.FLP)} Self-regulating Flippase under the regulation of the n-Synaptobrevin promoter. FLP sequence is flanked by two FRT-F15 sites, corresponding to low excising probability hence longer FLP activity. P{UAS-nBitbow.1.0}su(Hw)attP5 is an insertion at the P{CaryIP}su(Hw)attP5 site. P{UAS-gBitbow.1.0}su(Hw)attP5 is an insertion at the P{CaryIP}su(Hw)attP5 site. PBac{UAS-gBitbow.1.0}VK00027 is an insertion at the PBac{y+-attP-9A}VK00027 site. P{UAS-mBitbow.1.0}su(Hw)attP5 is an insertion at the P{CaryIP}su(Hw)attP5 site. PBac{UAS-mBitbow.1.0}VK00027 is an insertion at the PBac{y+-attP-9A}VK00027 site. PBac{nSyb(FRT13.FLP)}VK00027 is an insertion at the PBac{y+-attP-9A}VK00027 site. P{nSyb(FRT15.FLP)}attP2 is an insertion at the P{CaryP}attP2 site. P{UAS-hH2B.2xmNG}attP2 is an insertion at the P{CaryP}attP2 site. PBac{UAS-hH2B.2xmNG}VK00027 is an insertion at the PBac{y+-attP-9A}VK00027 site. P{UAS-hH2B.2xTagBFP}attP2 is an insertion at the P{CaryP}attP2 site. PBac{UAS-hH2B.2xTagBFP}VK00027 is an insertion at the PBac{y+-attP-9A}VK00027 site.
