1 Hour Lunch Break

This rigorous three day program is ideal for basic research and translational biology scientists who are looking for a balanced theoretical vs. hands-on introduction to gene editing iPSCs using CRISPR/Cas9. In this workshop, participants will be able to design CRISPR/Cas9 gene editing tools, deliver gene-editing tools into human iPSCs, and detect gene-editing events by PCR/ Surveyor Assay.
