Be more confident with your in vivo genome editing
When you want a quick way to verify the efficiency of your Cas9 mRNA transfections, SBI offers the hspCas9-T2A-GFP SmartNuclease™ mRNA (an RFP version is also available). This construct delivers coordinated translation of Cas9 and GFP from the same mRNA, enabling the use of the GFP signal to assess transfection efficiency.
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 hspCas9-T2A-GFP 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
- Enables assessment of Cas9 mRNA transfection efficiency through the GFP signal
- Delivers functionally validated Cas9 SmartNuclease
- Backed by expert, easy-to-reach technical support
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
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.
