False Positives.

There have been some cases when constructing deletions with the DrosDel kit of 'false positives', where the flip-in stage has resulted in red-eyed flies but not a deletion. This is most obvious to pick up on the X chromosome with w+ males, and can occur in the same cross that yields an actual deletion. We therefore encourage researchers either making their own deletions or receiving deletions from us to verify them by PCR and complementation testing with a known lethal. We are currently investigating this further.

Construction of a new Drosophila deletion collection and a European Drosophila network.

The objectives of this project are to develop new stocks of wide utility to researchers and to support a thematic network of Drosophila researchers. The stocks produced under this project will be published in FlyBase and be included in existing Drosophila Stock Centres in order to enhance the power of Drosophila genetics and, in particular, provide tools for the functional analysis of the Drosophila genome.

We request therefore that all new insertions and genetic aberrations produced from stocks provided by us are reported to FlyBase and made freely available to all in the Drosophila community.

Please inform us if you find a discrepancy between your data and that provided on our website.

DrosDel is funded by a grant from the European Union
