Assessing gene function in human B cells: CRISPR/Cas9‐based gene editing and mRNA‐based gene expression in healthy and tumor cells

Robust methods for manipulation of human B cells, isolated from healthy donors and patients with B cell disorders, has the potential to significantly accelerate B cell research. Our work describes a step-by-step protocol to perform electroporation-based screening of gene function in B cells through the use of Cas9 ribonuclecomplexes and in vitro produced mRNA.
