Overview

Stay on-target with your genome editing projects

For pre-clinical and other applications where you need to minimize off-target Cas9 activity and are using transfectable cells, All-in-one Cas9 SmartNickase and gRNA plasmids are an excellent choice.

CMV-T7-hspCas9-SmartNickase-H1-gRNA All-in-one Cas9 SmartNickase Plasmid

Unlike the wildtype Cas9 protein which introduces double-strand breaks (DSBs), the Cas9 SmartNickase introduces paired nicks at the gRNA-directed site. Creating nicks favors the higher-fidelity homologous recombination process over non-homologous end joining (NHEJ), with paired nicking shown to reduce off-target activity by 50- to 1,500-fold in cell lines, and to facilitate gene knockout in mice without losing on-target cleavage efficiency1.

  • Conveniently deliver Cas9 Nickase and gRNA with a single vector
  • Reduce off-target activity
  • Drive Cas9 Nickase expression with the CMV promoter, which provides high expression levels in many common cell lines (HeLa, HEK293, HT1080)
  • Express gRNA from the H1 promoter for maximum specificity and choice of targets
  • Ensure efficient import of Cas9 Nickase to the nucleus with N-term and C-term nuclear localization signals (NLSs)
  • Boost Cas9 Nickase gene expression and stabilize the transcript via the WPRE regulatory element after the C-term NLS
  • Easily detect and/or purify the Cas9 Nickase protein with the N-term myc-tag
  • Produce Cas9 Nickase mRNA via in vitro transcription using the convenient T7 promoter

As with all of our Cas9 Nickase delivery options, the CMV-T7-hspCas9-Nickase-H1-gRNA Plasmid is functionally validated and comes backed by our expert technical support team—if you’ve got a genome engineering question just ask by emailing tech@systembio.com.

Why an HR targeting vector is a recommended

Even though gene knock-outs can result from DSBs caused by Cas9 alone, SBI recommends the use of HR targeting vectors (also called HR donor vectors) for more efficient and precise mutation. HR donors can supply elements for positive or negative selection ensuring easier identification of successful mutation events. In addition, HR donors can include up to 6-8 kb of open reading frame for gene knock-ins or tagging, and, when small mutations are included in either 5’ or 3’ homology arms, can make specific, targeted gene edits.

CRISPR/Cas9 Basics

Through careful selection of the target sequence and design of a donor plasmid for homologous
recombination, you can achieve efficient and highly targeted genomic modification with CRISPR/Cas9.

The system

A quick overview of the CRISPR/Cas9 System.

Cas9 protein—uses guide RNA (gRNA) to direct site-specific, double-strand DNA cleavage adjacent to a protospacer adapter motif (PAM) in the target DNA.

gRNA—RNA sequence that guides Cas9 to cleave a homologous region in the target genome. Efficient cleavage only where the gRNA homology is adjacent to a PAM.

PAM—protospacer adapter motif, NGG, is a target DNA sequence that spCas9 will cut upstream from if directed to by the gRNA.

The workflow at-a-glance

DESIGN: Select gRNA and HR donor plasmids. Choice of gRNA site and design of donor
plasmid determines whether the homologous recombination event results in a knock-out,
knock-in, edit, or tagging.

CONSTRUCT: Clone gRNA into all-in-one Cas9 vector. Clone 5’ and 3’ homology arms into HR
donor plasmid. If creating a knock-in, clone desired gene into HR donor.

CO-TRANSFECT or CO-INJECT: Introduce Cas9, gRNA, and HR Donors into the target cells
using co-transfection for plasmids, co-transduction for lentivirus, or co-injection for mRNAs.

SELECT/SCREEN: Select or screen for mutants and verify.

VALIDATE: Genotype or sequence putative mutants to verify single or biallelic conversion.

Supporting Data

Simultaneous editing at multiple genomic locations

The Multiplex gRNA Cloning Kit enables efficient delivery of four gRNAs

Figure 2. The Multiplex gRNA Cloning Kit enables efficient delivery of four gRNAs. (A) We used a quad-plex gRNA created using the Multilplex gRNA Cloning Kit and an All-in-one Cas9 SmartNickase Vector to remove a (B) 1260 bp GFP-T2A-RFP segment from a cell line with a stably integrated CMV-GFP-T2A-RFP expression cassette. We cloned the four gRNAs into a Cas9 SmartNickase vector (EF1Nickase-H1-gRNA) to guide two double nicking events—one at the 5’ end of the GFP and the other at the 3’ end of the RFP gene. (C) PCR assays with primers just outside of the GFP and RFP genes generate a 1600 bp fragment in the absence of the SmartNickase vector (lane 1), and a 340 bp fragment in the presence of the Cas9 SmartNickase-4 gRNA construct (lane 2), demonstrating the efficiency of SmartNickase-mediated paired double-nicking and GFP-T2A-RFP genomic deletion. (D) Deletion of both GFP and RFP activities can also be seen in a functional assay, through reduction in both GFP and RFP fluorescence.
