The following information accompanied stocks donated to the Bloomington Drosophila Stock Center by Olena Riabinina and Christopher Potter, The Johns Hopkins University School of Medicine. P{n-syb-QF2.P} expresses a new and less toxic variant of QF (QF2) pan-neuronally under the control of n-syb. P{n-syb-QF2.P}attP2 is a semi-viable insertion on the third chromosome in an attP site at 68A4, 3L:11063638 . M{n-syb-QF2.P} expresses a new and less toxic variant of QF (QF2) pan-neuronally under the control of n-syb. M{n-syb-QF2.P}ZH-86Fb is an insertion on the third chromosome in an attP site at 86F8, 3R:7634081 . P{alphaTub84B-QF2.P} expresses a new and less toxic variant of QF (QF2) under the control of alphaTub84B. P{alphaTub84B-QF2.P}1 is a semi-viable insertion on the third chromosome. P{alphaTub84B-QF2.P}2b is a semi-viable insertion on the second chromosome. P{n-syb-QF2w.P} expresses a variant of QF2 that is a weaker transactivator (and shows slightly less toxicity than QF2 when ubiquitously expressed) under the control of n-syb. P{n-syb-QF2w.P}attP2 is a viable insertion on the third chromosome in an attP site at 68A4, 3L:11063638 . P{Act5C-QF2w.P} expresses a variant of QF2 that is a weaker transactivator (and shows slightly less toxicity than QF2 when ubiquitously expressed) under the control of Act5C. P{Act5C-QF2w.P}2b is an insertion on the second chromosome. P{alphaTub84B-QF2w.P} expresses a variant of QF2 that is a weaker transactivator (and shows slightly less toxicity than QF2 when ubiquitously expressed) under the control of alphaTub84B. P{alphaTub84B-QF2w.P}2 is an insertion on the second chromosome. P{alphaTub84B-QF2w.P}6 is an insertion on the third chromosome.
