CRISPR/Cas9 delivery methods
For gene editing in mammalian cells we typically recommend delivery of a ribonuclear protein (RNP) complex consisting of Cas9 protein and a single guide RNA (sgRNA). RNPs remain in the cell for a short time and the dose is minimal, leading to lower toxicity and reduced editing at off-target sites compared to other methods.
RNPs can be delivered using either electroporation of recombinant Cas9 protein along with in vitro transcribed guide RNA or using cell-derived nanovesicles called gesicles. We also provide kits for delivery using lentivirus, AAV, and plasmid. See the links below for articles and tech notes related to delivery of CRISPR/Cas9 elements.
