USING TRUNCATED GUIDE RNAS (TRU-GRNAS) TO INCREASE SPECIFICITY FOR RNA-GUIDED GENOME EDITING

摘要

CRISPR-Cas genome editing uses a guide RNA, which includes both a complementarity region, which binds the target DNA by base- pairing, and a Cas9-binding region, to direct a Cas9 nuclease to a target DNA. Further disclosed are methods for increasing specificity of RNA-guided genome editing using CRISPR/Cas9 systems by using truncated guide RNAs (tru-gRNAs).
