Webb5 aug. 2014 · The advantage is that off-target sites of the two individual gRNAs are unlikely to be close together and therefore only lead to DNA nicks, which have low mutagenic potential. We have recently demonstrated that an act-cas9D10A nickase can be used in combination with our pCFD4 vector for fly genome engineering (15). WebbSynthego’s design tool offers fast and easy design of sgRNAs that generate up to 97% editing efficiency and the lowest off-target effects from a library of over 120,000 …

Cas9 are modular DNA-binding proteins that can recognize a customized DNA-sequence when programmed with a complementary gRNA molecule. WebbThe gRNA is a short synthetic RNA composed of a scaffold sequence necessary for Cas-binding and a user-defined ∼20 nucleotide spacer that defines the genomic target to be …

The methods used to identify off-target sites fall into two categories: Empirical methods (e.g., GUIDE-seq [1], CIRCLE-seq [2], Digenome-seq [3], DISCOVER-seq [4], or other empirical methods ...
Webb2 jan. 2014 · A new strategy for gene targeting using two gRNAs (paired-gRNA) instead of a single gRNA was recently reported to reduce off-target effects; in this system, the Cas9 protein is mutated from its original nuclease form to a …
