FREE samples of HolFast holidic diet (30.09.2025). No samples left due to the high demand!!
A new holidic (chemically defined) diet for Drosophila called HolFast was recently designed by Sebastian Sorge et al. HolFast has wide applications in nutritional and metabolic studies of Drosophila development.
It is optimised for fast reproducible larval development. So, it's now possible to test the effects on larvae, as well as adult flies, of adding more or less of any pure dietary macro- or micro-nutrient, including individual amino acids.
The VDRC will be distributing samples of freeze-dried HolFast, each enough for 100ml of diet, to the fly community. Just add warm agarose solution and dispense into vials. HolFast has been successfully used in three independent labs but we would very much like to get your feedback on it too. Twenty samples will be distributed on a first-come first-served basis with a maximum of two samples per lab. If you'd like to try a free sample (only shipping costs to be paid) please email [email protected]

About the Vienna Drosophila Resource Center (VDRC)
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 main 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.
Resources
The VDRC is the main Drosophila melanogaster stock center in Europe and our primary role is to maintain and distribute unique transgenic fly lines to researchers at the Vienna BioCenter and worldwide. We currently maintain more than 30,000 independent lines, nearly all in duplicate, and have successfully shipped over 1.3 million lines to over 2.500 labs internationally.
We have the world's largest collection of Drosophila RNAi lines, enabling genome-wide screens. Other collections include lines for CRISPR technology, enhancer-GAL4 drivers, tagged constructs, mutant alleles, reporters and RNAi plasmids.
