Dear Editor,CRISPR and CRISPR-associated (Cas) proteins play their adaptive immunity role in degrading foreign nucleic acids in both bacteria and archaea.CRISPR/Cas has proved efficient in modifying mammalian genomes (Cong et al.,2013;Mali et al.,2013) and various delivery methods for Cas9:gRNA complex have been established.Among different delivery means,in vitro transcribed Cas9 mRNA/gRNA,purified Cas9 protein,and adeno-associated virus (AAV) driven seem promising toward clinical applications (Kouranova et al.,2016;Lin et al.,2014;Yin et al.,2016).Still,all the fore-mentioned methods for delivering CRISPR/Cas9 have certain shortcomings./n vitro transcription and protein purification are complicated and inconvenient for use,while AAV mediated system suffers from the side effects of immune response and insertional mutagenesis (Donsante et al.,2007;Li et al.,2011).
