We present a 10-fold faster, accurate, and more efficient (FAME)-CRISPR-Cas9 gene editing workflow utilizing histone deacetylase inhibitor (HDACi)-mediated chromatin relaxation and engineered virus-like particle (eVLP) delivery of Cas9. We describe steps for optimizing HDACi concentration, euchromatinization timing, and Cas9 delivery/expression to improve CRISPR-Cas9 editing efficiency and efficacy. This protocol can eliminate the need for single-cell cloning and reduce experimental timelines up to 10-fold while minimizing HDACi-mediated toxicity. For complete details on the use and execution of this protocol, please refer to Djamshidi et al.1.
