This course will provide training in genome editing and cell engineering in mammalian cells and mouse embryos using the highly efficient CRISPR/Cas9 system. Participants will learn design of CRISPR targets using bioinformatics tools, generation of gene knock-outs/knock-ins, and target validation using the most current technologies. The course will be split into two groups (mammalian cells OR mice) based on participants’ expertise. Please note that all participants are expected to engage in all sessions. Participants should plan for approximately 1 hour extra per day for self paced learning modules.
