该研究发现IS200/IS605转座子家族与独特的ncRNA相关,编码可编程RNA引导型核酸酶IscB,IsrB和TnpB(统称为Ω),其中IscB和TnpB可能是CRISPR核酸内切酶Cas9s和Cas12s的祖先。 Fig. 1. IscBs are associated with ncRNAs of unknown function....
For the myeloid lineage, Surveyor nuclease assay was performed with primers in Table S4, according to the manufacturer protocol (Integrated DNA Technologies, Cat. No. 706020) (Table S4. sgRNAs; media and cytokines; and antibodies used in flow cytometry panels in CD34+ experiments. Related to ...
XCAS9 is a CAS9 variant with potentially higher fidelity and broader compatibility, and dCAS9 is a CAS9 variant without nuclease activity. We show that XCAS9 and dCAS9 also interact with KU86 and disrupt DNA DSB repair. Considering the critical roles of DNA-PK in maintaining genomic stability...
Other recently developed approaches for inducing targeted mutations include hit and run, double replacement, and PiggyBac recombinase systems, and the use of engineered nuclease pairs such as ZFNs or TALENs. These advances allow virologists to apply techniques, previously limited to virus manipulation,...

The canonical PAM sequence associated with the Cas9 nuclease of Sreptococcus pyogenes, which is most commonly used in CRISPR, is 5’-NGG-3’, where “N” is any nucleobase followed by two guanines. Cas9 proteins from other organisms are associated with other different PAMs. ...
Briefly, ArciTect™ CRISPR-Cas9 RNP Complex solution was generated with 60 μM gRNA and tracrRNA and 3.6 µg ArciTect™ Cas9-eGFP Nuclease. Afterwards, 20 µM single-strand oligodeoxynucleotide (ssODN) was added to the RNP solution. The following gRNA was used to target TFR2 ...
