PBac{PB} insertion lines from Exelixis were remapped and assessed for inclusion in the Gene Disruption Project collection; flanking sequence data were submitted to GenBank.
A set of transgenic insertion stocks derived by TE mobilization using the Tni\piggyBac-based construct PBac{PB}. The PBac{PB} construct carries the w+mC mini-white marker flanked by short (48-bp) Scer\FRT recombination sites.
Original line may have contained 3 insertions (76A3-4, 93F14, 21F1). The Bloomington stock does not carry a 2nd chromosome insertion.
Location 3L:19251866-19251867 confirmed by FlyBase alignment of dbGSS accession CZ468157 to D. melanogaster arm Release_4 and heterochromatin Release_3.2b. Insertion orientation confirmed.
