In the field of genetic engineering, the modification of genes to produce stable cell lines has a variety of applications ranging from the development of novel therapeutics to patient specific treatments. To successfully generate a cell line, the gene of interest must be delivered into the cell and integrated into the genome. The efficiency of cell line generation systems therefore depends on the efficiency of delivery of genetically modifying molecules such as plasmids and CRISPR/CAS9 complexes. In this work, we describe a localized electroporation-based system to generate stable monoclonal cell lines. By employing the nanofountain probe electroporation (NFP-E) system, single cells in patterned cultures are selectively transfected with plasmids, grown, and harvested to obtain stably expressing cell lines. Methods for microcontact printing, cell culture, electroporation, and harvesting are detailed in this chapter.
