Leading news, knowledge, and industry trends in genetic research

Large-scale gain-of-function screens have not yet shown the same popularity as loss-of function experiments, mainly due to logistical complications of using the traditional reagents (ORFs). Here we explain the hurdles to setting up a high-throughput ORF screen, and how CRISPRa offers a new solution that can expand the screening toolbox to maximize your window of discovery.
