Summary: hTERT-RPE1 cells are genetically stable near diploid cells widely used to model cell division, DNA repair, or ciliogenesis in a non-transformed context. However, poor transfectability and limited homology-directed repair capacity hamper their amenability to gene editing. Here, we describe a protocol for rapid and efficient generation of diverse homozygous knockins. In contrast to other approaches, this strategy bypasses the need for molecular cloning. Our approach can also be applied to a variety of cell types including cancer and induced pluripotent stem cells (iPSCs).
