In this tutorial video, we demonstrate the process of conducting a HPRT gene knock-out experiment in a HEK293 adherent cell line. Learn how to design the experiment; prepare both cells and reagents; conduct post-transfection assessment; perform genomic cleavage detection; and isolate and clonally expand the culture for further experimentation.
