Protocol for generating monoclonal CRISPR-Cas9-mediated knockout cell lines using RNPs and lipofection in HNSCC cells.

ABSTRACT: CRISPR-Cas9 is a powerful technology for accurate and optimizable genome editing. Here, we present a protocol for generating monoclonal knockout (KO) cell lines using CRISPR-Cas9, ribonucleoprotein complexes (RNPs), and lipofection in adherent HNSCC cells from start to finish. We describe steps for choosing the suitable guide and primer design, preparation of guide-RNA (gRNA), lipofection of RNP complexes in HN cells, and single-cell cloning with limiting dilution. We then detail PCR and DNA purification and the selection and verification of monoclonal KO cell lines.
