Overview

Accelerating in vivo genome editing

From basic biological studies to generating novel disease models, SBI’s injection- and transfection-ready PrecisonXTM Cas9 SmartNucleaseTM mRNA is here to move your in vivo genome engineering projects forward faster.

Use with an appropriate gRNA and, if your application needs it, a homologous recombination (HR) targeting vector for gene knock-ins, knock-outs, editing, and tagging. The Cas9 SmartNuclease will generate a double-strand break (DSB) at the site specified by the gRNA, and this DSB can be efficiently and precisely repaired in a manner that includes your desired mutation through the use of an HR targeting vector.

As with all of our Cas9 delivery options, the Cas9 SmartNuclease mRNA 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.

  • Ready to use for in vivo genome editing applications
  • Functionally validated Cas9 SmartNuclease
  • Backed by expert, easy-to-reach technical support

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.

Efficiently generate gRNA with the T7 gRNA SmartNuclease Synthesis Kit

Pair your Cas9 SmartNuclease mRNA with our T7 gRNA SmartNuclease Synthesis Kit, which comes with a pre-linearized, ready-for-cloning gRNA expression vector and all the reagents you need for T7-driven in vitro transcription of your cloned gRNA.

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

Knock-in of GFP at the AAVS1 Safe Harbor Site using Cas9 SmartNuclease mRNA

Cas9 SmartNuclease mRNA is used to knock-in GFP to the AAVS1 Safe Harbor Site

Figure 1. Cas9 SmartNuclease mRNA-mediated knock-in of GFP to the AAVS1 Safe Harbor Site. METHODS: The AAVS1 gRNA sequence was cloned into the T7 gRNA Cloning and Production Vector and in vitro transcribed. These gRNAs were co-transfected with the Cas9 synthetic mRNA in combination with an AAVS1 HR Targeting Vector harboring a GFP marker. The activities of the Cas9 mRNA + AAVS1 gRNA transfection was compared with that of the EF1 Cas9 SmartNuclease-AAVS1 gRNA All-in-one vector system. Cells were imaged for GFP fluorescence after 3 days.
