CRISPR-Cas9 technology allows for rapid, targeted genome editing at nearly any loci with limited off-target effects. Here, we describe a method for using retroviral transduction to deliver single-guide RNA to primary bone marrow-derived macrophages. This protocol allows for high-throughput reverse genetics assays in primary immune cells and is also compatible with retroviral systems for transgene expression.
