Payment information

Prices will be increased by 10% from 1st April 2022. The increase is in line with inflation since our last price adjustment in 2019.

Subsidized fees

The Vienna Drosophila Resource Center (VDRC) is part of the Vienna Biocenter Core Facilities (VBCF), a non-profit research company, publicly funded by the Austrian Federal Ministry of Education, Science and Research, and the City of Vienna via the Vienna Business Agency.

Austria currently represents less than 2% of the total VDRC usage, (with US ~40%, Europe ~40% and Asia ~15%). The VBCF funding covers approximately 25% of our running costs with the remainder coming from user fees.

We would like to emphasize that your costs are subsidized by Austrian grant funding and you are not being asked to cover the full cost.
