Vienna Drosophila Resource Center
The Vienna Drosophila Resource Center (VDRC) is a professionally organized bioresource center of international significance that aims to promote scientific discoveries in Drosophila melanogaster. Our primary aim is to maintain unique transgenic Drosophila stocks and DNA resources and to distribute them both locally and worldwide. We also acquire, create, and develop new resources, according to emerging new technologies and the needs of the local and international Drosophila research community.
The VDRC is the only Drosophila melanogaster stock center in Europe and our main role is to maintain and distribute unique transgenic fly lines to researchers at the Vienna BioCenter and worldwide. We currently maintain more than 31,000 independent lines, nearly all in duplicate, and have successfully shipped over 1.3 million lines to over 2.500 labs internationally.
We have the largest world's collection of Drosophila RNAi lines, enabling genome-wide screens. Other collections include enhancer-GAL4 driver lines, tagged constructs, mutant alleles, and reporters.
We can ship to any Drosophila researcher who has obtained a VDRC log-in.
For more information and stock ordering go to www.vdrc.at.
In addition to maintaining transgenic fly stocks, the VDRC is a repository for plasmid DNAs which are of use in Drosophila melanogaster research. We can ship plasmids to any Drosophila researcher who has obtained a VDRC log-in.
We currently have 13,840 DNA constructs used to generate the GD RNAi transgenic fly collection. These are long hairpin constructs for a specific gene inserted in the pMF3 vector (see GD library cloning strategy).
In addition, we have a small collection of plasmids, useful for Drosophila research, which have been deposited by other research groups.
The VDRC is open to donations of highly used Drosophila stocks for integration into its community stock center collection for distribution to all fly researchers. In addition, we offer a private stock keeping service where we maintain and distribute your personal fly stock/plasmid collections on your behalf. See here for information about the VDRC Stock Keeping Policy.
If you wish to donate resources to the VDRC or use our private stock keeping service, please contact us to discuss the options as early as possible: firstname.lastname@example.org.
The VDRC Fly Food Kitchen (FFK) provides fly groups in the Vienna region with media required for maintaining live Drosophila stocks. The kitchen has the capacity to produce volumes of up to 240 liters of fly media per day, with typically 1,200,000 small tubes and 350,000 bottles produced per year.
We produce different media types in tubes and bottles, with various plugging options.
The VDRC has the largest collection of Drosophila RNAi lines worldwide. The genome-wide resource enables large-scale genetic screens and loss-of-function experiments in essentially any tissue or cell at any stage in the life of the organism.
When crossed with a GAL4 'driver' line, the UAS-RNAi stock induces expression of a specific hairpin structure, which silences expression of the target gene via RNA interference (RNAi).
Our RNAi resource of nearly 27,000 stocks (91% genome coverage) includes transgenic UAS-RNAi stocks with long hairpins (GD and KK libraries) and short hairpin microRNAs (shRNA library).
See here for further details about the RNAi libraries.
GAL4 lines are one part of the binary GAL4-UAS system (Brand and Perrimon, 1993). Our Vienna Tiles (VT) enhancer Gal4 lines are typically used in Drosophila experiments as ‘drivers’ to restrict the expression of a UAS line (e.g., UAS-RNAi) to a specific subset of cells or developmental time-point.
Each line contains a short fragment of genomic DNA controlling GAL4 expression and the constructs are integrated at a single defined genomic position (attP2). Precise expression patterns of reporters driven by these lines have been extensively documented and annotated in the embryo and adult brain.
In addition to maintaining and distributing transgenic fly lines, the VDRC also acts as a repository for plasmids that are useful for Drosophila research.
Currently we have 13,840 DNA constructs used to generate the GD RNAi transgenic fly collection (see DNA construct list). These are long hairpin constructs for a specific gene inserted in the pMF3 vector (see GD library cloning strategy).
In addition, we have a small collection of plasmids useful for Drosophila research that have been deposited by research groups outside of the VDRC and we aim to add to this collection. See Other Resources.
The Tagged FlyFos TransgeneOme (fTRG) library consists of transgenic flies for analysis of gene function and protein localization. Each line has been engineered to tag a specific protein with a multi-epitope tag at its C-terminus, for use in a variety of downstream applications, including live imaging, subcellular localization, and interaction proteomics of selected gene products at all stages of Drosophila development.
Full details about creation of the fTRG lines can be found in the following publication: A genome-wide resource for the analysis of protein localisation in Drosophila, Sarov et al (2016).
For further information about the fTRG lines, see here.
In addition to maintaining and distributing transgenic fly stocks and plasmids owned by the VDRC, we also maintain Drosophila resources owned by other organizations and distribute them to the scientific community on behalf of the depositor ('Provider Scientist') via the regular VDRC webshop. For more information see About Other Resources.
The resources can be either transgenic flies or plasmid DNA and currently include mutant alleles, tagged constructs, RNAi lines, reporters, and CRISPR/Cas9 plasmids.
Further fly stocks/plasmids will be added to the 'Other Resources' section if the 'Provider Scientist' wishes to make them available to researchers with a VDRC login.
- Fly food must be ordered online via MyVBCF.
- To order fly stocks, log into the VDRC website using your username & password. If you do not have a username yet, please register first. See here for details.
- All fly orders will be shipped by courier, but researchers in the Vienna area may come and collect their order in person.
- If you wish to discuss donating stocks to the VDRC, or using the Private Stock Keeping Service, please contact email@example.com
Continuation of funding for VDRC by the City of Vienna and the Austrian Ministry of Science is dependent on documented evidence of contributions to scientific output. Therefore, please acknowledge the VDRC when you obtain resources from us by including the following statement either in the Materials and Methods or the Acknowledgements section of your publication:
Transgenic fly stocks and/or plasmids were obtained from the Vienna Drosophila Resource Center (VDRC, www.vdrc.at).
Citing RNAi lines:
- For GD RNAi lines, please cite Dietzl et al [Nature 448,151-156,12 Jul 2007] and acknowledge the VDRC.
- For other lines, please acknowledge the Principal Investigator and cite the appropriate publication for each resource, as listed on our website: www.vdrc.at.
