The following information accompanied stocks donated to the Bloomington Stock Center by Wei Gong and Kent Golic, University of Utah (11/04).
Hsp70Ba304 is a deletion of the Hsp70Ba gene produced by ends-out gene targeting. The miniwhite marker has not been removed by Cre-mediated recombination.
Df(3R)Hsp70A is a deletion of the Hsp70 genes at 87A (Hsp70Aa and Hsp70Ab) produced by ends-out gene targeting. The miniwhite marker has not been removed by Cre-mediated recombination.
Df(3R)Hsp70B is a deletion of the Hsp70 genes at 87C (Hsp70Ba, Hsp70Bb, Hsp70Bbb and Hsp70Bc) produced by ends-out gene targeting. The miniwhite marker has not been removed by Cre-mediated recombination.
The donor templates and technique used to generate these lines are described in Gong and Golic, 2004, Genetics 168(3): 1467-1476 (FBrf0180286). Hsp70Ba304 is one instance of the targeted deletion class described as Hsp70Ba- in this paper. Likewise, Df(3R)Hsp70A is a representative Hsp70A- event and Df(3R)Hsp70B is a representative Hsp70B- event.
Two recombinant chromosomes have also been donated to the Stock Center:
1. combination of an Hsp70A- deletion (Df(3R)Hsp70A) and a Hsp70Ba- deletion (Hsp70Ba304).  In this chromosome, the miniwhite markers inserted during gene targeting have not been removed.
2. combination of an Hsp70- deletion (Df(3R)Hsp70A) and an Hsp70B- deletion (Df(3R)Hsp70B). In this chromosome, the miniwhite markers inserted as part of the gene targeting event have been removed by Cre-mediated recombination.
