Overview

Stay on-target with your genome editing projects

All-in-one Cas9 and gRNA plasmids are an excellent way to simplify delivery of your CRISPR/Cas9 system by providing both Cas9 and gRNA from a single vector. Unlike our newer Cas9 constructs, this first generation Cas9 SmartNuclease—CMV-hspCas9-H1-gRNA All-in-one Cas9 SmartNuclease Plasmid—does not contain a selectable marker for identifying transfected cells and is now available as an intact, circular plasmid.

CMV-hspCas9-H1-gRNA All-in-one Cas9 SmartNuclease Plasmid (circular)

 

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

As with all of our Cas9 SmartNuclease delivery options, the CMV-hspCas9-H1-gRNA All-in-one Cas9 SmartNuclease 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

Validating SBI’s CRISPR/Cas9 SmartNickase and Null Nuclease Vectors

The All-in-one Cas9 SmartNickase Vector shows genome editing activity

Figure 1. The All-in-one Cas9 Null Nuclease Vector shows no genome editing activity. We compared the activity of wild-type Cas9 (EF1α-hspCas9-H1-gRNA All-in-one SmartNuclease Plasmid, Cat.# CAS900A-1), Cas9 SmartNickase (EF1α-hspCas9-nickase-H1-gRNA All-in-one SmartNickase Plasmid, Cat.# CAS800A-1), and Cas9 Null Nuclease (EF1α-hspCas9-DM-H1-gRNA All-in-one Cas9 Null Nuclease Plasmid, Cat.# CAS805A-1) to insert a GFP reporter at the AAVS1 site through the use of AAVS1-targeting gRNA and an AAVS1-targeting HR Targeting Vector (AAVS1 Safe Harbor cDNA/miRNA Targeting HR Donor Vector (pAAVS1D-PGK-MCS-EF1α-copGFPpuro), Cat.# GE602A-1).
(Left panel) Fluorescence (left-most column) and bright field (right-most column) microscopy showing that both Cas9 SmartNuclease (top set) and Cas9 SmartNickase (middle set) are able to insert GFP into the genome, whereas the Cas9 Null Nuclease is not (bottom set).
(Right panel) A Surveyor Nuclease Assay corroborates the lack of genome editing capabilities of the Cas9 Null Nuclease. The lack of cleavage seen in the SmartNickase lane is likely due to the lower frequency of GFP insertion.
