So you want to do a CRISPR pooled screen in insect cells? You can! Here's how

May 12, 2022

At the DRSC-BTRR, we've been doing a lot of pooled-format CRISPR knockout screens in Drosophila cells. We're finding the results to be robust and reproducible. And best of all, the results have been informative, providing insights into diverse areas of biology.

Thinking about how to do CRISPR knockout screens in cells is a little different from thinking about how to do a genetic or RNAi screen in vivo or doing an arrayed-format RNAi screen....

Transgenic Fly Stocks for Double Knockout of Paralog Pairs

May 18, 2020

Paralogs can be defined as related genes within a genome that are thought to arise from gene duplication events. Because paralogous proteins share amino acid identity, they can have redundant functions. But the picture is not necessarily so straightforward. Indeed, there are examples in which paralogous genes have distinct functions in some tissues, and overlapping functions in others.

The DRSC/TRiP is engaged in a project in collaboration with the Perrimon and Bellen labs to generate resources useful for the study of paralogous genes in Drosophila.

Shut-down in response to COVID-19

March 15, 2020

In adherance with Harvard Medical School's response to the COVID-19 pandemic, the DRSC/TRiP-FGR and DRSC-BTRR will be closing our doors by 5 pm on Wed. March 16.

Services will be unavailable for at least 6-8 weeks but leaders and staff will be reachable by email, and related resources are available at the BDSC and DGRC in Indiana, and at Addgene, and information remains available at this site.

We are focused right now on minimizing the impact of the shut-down on our activities. In the future, we expect to be able to make use of the time to help our research...
