Left Arm Region Genome
Targeting/Cloning PlanTargeting Construct Cloning:● PCR amplification of left and
right homologous arms● Synthesized 2A-H2BmKO2
○ Cloning of these components together
● Verify Sequence
CRISPR:● Design gRNAs with crispr.mit.
edu CRISPR design tool and clone following Church Lab’s gRNA Synthesis Protocol
● Transfect into HEK293T cells and run ddPCR to test gRNA efficiency and establish protocol
● Transition to iPS cells and co-transfect with targeting construct
