The Vienna Drosophila Resource Center (VDRC) is a professionally organized bioresource center which aims to promote scientific discoveries in Drosophila, primarily by maintaining transgenic Drosophila melanogaster stocks and DNA resources and distributing them to Drosophila researchers both locally and worldwide. VDRC was established in April 2007 as a non-profit research infrastructure by the IMP and IMBA at the Campus Vienna Biocenter. Its mandate is to maintain and distribute the transgenic RNAi stocks constructed by Dickson and Keleman groups at the IMP. From March 1, 2011, the VDRC formally became independent of IMP and IMBA and joined the Campus Science Support Facilities (CSF). With this move the VDRC became part of Austria’s first long-term funding for research infrastructure. Currently approximately half of the VDRC operating costs are covered by user fees, the other half by funding of the Austrian Federal Government (bm.wf) and the City of Vienna.
