Generation of Knock-out Primary and Expanded Human NK Cells Using Cas9 Ribonucleoproteins

Here, we present a protocol to genetically modify primary or expanded human natural killer (NK) cells using Cas9 Ribonucleoproteins (Cas9/RNPs). By using this protocol, we generated human NK cells deficient for transforming growth factor–b receptor 2 (TGFBR2) and hypoxanthine phosphoribosyltransferase 1 (HPRT1).
