caging strategy for crRNA
Engineering MethodThe caging strategy for crRNA is a photoregulated CRISPR/Cas9 control method in which vitamin E is coupled to the 5' terminus of crRNA through a photolabile linker. In the caged state, the modified crRNA is reported to suppress target DNA association while preserving Cas9/crRNA/tracrRNA ribonucleoprotein assembly, and light irradiation restores genome-editing activity.
