Electroporation of CRISPR-Cas9 into Malignant B Cells for Loss-of-Function Studies of Target Gene Via Knockout

CRISPR-Cas9 is a unique technology that enables geneticists and medical researchers to edit genomic DNA for studying biology, pathogenesis, and molecular basis of treatment in malignant B cells. Unfortunately, malignant B cells are extremely difficult to transfect by most traditional methods. In this chapter, we describe the use of the Nucleofector™ Technology-based electroporation system with optimized transfection conditions for generating a malignant B cell model, JEKO-1, with ROR1-gene knockout via CRISPR-Cas9 technology.
