Variable Dose Analysis: a new DRSC-supported cell screen approach that leverages existing reagents to perform robust screens

December 1, 2017

We are excited to report the publication of a paper from Benjamin Housden and colleagues describing development and use of the Variable Dose Analysis (VDA) approach. Ben developed a way to use existing TRiP shRNA plasmids originally developed for fly stock production in a new, effective approach to high-throughput cell screening.

The VDA approach is particularly useful for combinatorial approaches that are acutely sensitive to assay robustness. The screen Ben and colleagues report focused on synthetic effects in Drosophila tumor model cells.  The...

Francois Payre's plenary talk at ADRC 2017 features results from DRSC cell-based screen

March 30, 2017

Those of us lucky enough to be at the Annual Drosophila Research Conference this morning saw a great talk by Francois Payre about regulation of Shavenbaby by small ORFs. A genome-wide cell-based screen done at the DRSC by Emilie Benrabah identified the mechanism of regulation. As this exemplifies, cell screens can help identify key pathways and factors that can then be followed up with in vivo studies.

New stocks added to the TRiP in vivo RNAi library

January 6, 2017

The TRiP has updated and curated our list of in vivo RNAi reagents for gene knockdown in fruitflies. To date, we have produced over 13,000 stocks for the benefit of the scientific community.

Visit the in vivo RNAi fly stocks and vectors page to download an excel file with the full list of fly stocks now available for order from the Bloomington Drosophila Stock Center (BDSC) and the...

CRISPR sgRNA design tool now based on Drosophila genome assembly 6

December 21, 2016

We have updated our CRISPR sgRNA design tool. The results and JBrowse display are now based on Drosophila melanogaster FlyBase genome assembly release 6. We have also added seed scores in addition to efficiency prediction scores and other values available on detailed views of sgRNA designs. Quick tips: start a search with a gene symbol or other identifier, use the...
