CRISPR-Cas9 Genome Editing in Human Cell Lines with Donor Vector Made by Gibson Assembly

CRISPR Cas9 genome editing allows researchers to modify genes in a multitude of ways including to obtain deletions, epitope-tagged loci, and knock-in mutations. Within 6 years of its initial application, CRISPR-Cas9 genome editing has been widely employed, but disadvantages to this method, such as low modification efficiencies and off-target effects, need careful consideration. Obtaining custom donor vectors can also be expensive and time-consuming. This chapter details strategies to overcome barriers to CRISPR-Cas9 genome editing as well as recent developments in employing this technique.
