Stock Keeping

VDRC is open to donations of highly used Drosophila stocks for integration into its community stock center collection. In addition, we offer a private stock keeping service where we will maintain and distribute your personal fly stock/plasmid collection on your behalf.


Policy for VDRC stock keeping services

Vienna Drosophila Resource Center (VDRC) is a non-profit research infrastructure whose immediate goal is to maintain and distribute transgenic RNAi lines and other resources to Drosophila researchers, both locally and world-wide. In future, we wish to further develop and expand our resources according to the emerging new technologies and community needs. Towards this goal we are open to donation of resources to add to our public collection as part of our "community stock center" service. In addition we offer a "private stock keeping service" where we will maintain personal stock collections on your behalf at your own cost.


Community Stock Centre

Under this service you have the possibility of donating your stocks to VDRC for integration into our public collection, if they are considered of broad enough interest to the Drosophila research community. Subject to scientific and financial approval, VDRC will take over ownership of the lines and will maintain and distribute the stocks. Your lines must be fully public, preferably with a publication accepted, and will be made available to the whole research community via the VDRC online ordering system.

For this service, the following conditions apply:

  • The lines, plus all essential information required by users to select them, are fully public.
  • VDRC takes full ownership and full financial risk for the lines.
  • As the owners, VDRC has the freedom to distribute lines to any researcher for any purpose, set fees as they see fit and decide which lines are no longer financially viable. For the lines deemed financially non-viable, there are two options:
    a) VDRC has the right to discard any lines after first offering them back to the donor.
    b) VDRC will continue to maintain them on condition that a party (e.g. the original donor) covers the difference between the income generated by these lines (from user fees) and the full costs of maintaining them.


Private Stock Keeping Service

VDRC offers to maintain your personal stock collection on your behalf and will accept both published and unpublished resources. This service may be useful if you have valuable stocks which you do not use regularly but do not want to discard, or if you spend time shipping stocks or plasmids to other labs and would like VDRC to do this on your behalf.

For this service, the following conditions apply:

  • Full maintenance and distribution costs (staff, consumables, overheads) must be paid by the owner, with no financial burden or risk for VDRC.
  • The stocks are private and are not owned by VDRC. The depositor remains the owner.
  • Stocks are maintained and distributed by VDRC on behalf of the owner.
  • Stocks will not be made publicly visible via VDRC unless specifically requested.
  • Those stocks which the owner wishes to be fully visible will be made available for ordering by any registered VDRC user.
  • Stocks which the owner does not wish to be publicly visible cannot be ordered via the VDRC website. VDRC cannot accept orders for these stocks directly, but will send stocks anywhere at the request of the owner, with shipping at the recipient's expense.
