STAMPScreen: An Integrated Pipeline for Mammalian Genetic Screening. STAMPScreen: An Integrated Pipeline for Mammalian Genetic Screening

With the recent advancements in genome editing, next generation sequencing (NGS), and scalable cloning techniques, scientists can now conduct genetic screens at unprecedented levels of scale and precision. With such a multitude of technologies, there is a need for a simple yet comprehensive pipeline to enable systematic mammalian genetic screening. In this study, we develop novel algorithms for target identi fication and a toxin-less Gateway cloning tool, termed MegaGate, for library cloning which, when combined with existing genetic perturbation methods and NGS-coupled readouts, enable versatile engineering of relevant mammalian cell lines. Our integrated pipeline for Sequencing-based Target Ascertainment and Modular Perturbation Screening (STAMPScreen) can thus be utilized for a host of cell state engineering applications. Overall design: 4 independent biological samples are analyzed. GFP or ZGLP1 was induced via docycyline in female hiPSCs in biological duplicates. GFP is used as a control for ZGLP1 induction.
