How It Works

Synthesizing gRNA

The workflow at-a-glance  

  1. Design two DNA oligonucleotides that are sense and antisense sequences of the target DNA and are immediately upstream of a PAM sequence (5’ – NGG – 3’)
  2. Anneal the two oligonucleotides to generate a duplex
  3. Ligate the duplex into the pre-linearized T7 gRNA SmartNuclease Cloning and Production Vector
  4. Transform into competent cells and grow in LB/Kanamycin plate (50 µg/ml)
  5. Confirm positive clones by direct sequencing
  6. Perform in vitro transcription (IVT) with the T7 SmartNuclease™ gRNA Synthesis Kit (Cat.# CAS510A-KIT)

Selecting Target DNA Sequences

The selection of the target DNA sequence is not limited by any constraints, with exception of the requirement of a PAM sequence in the form of 5’ – NGG – 3’ (where N = any base) immediately following the target sequence. The typical length of the target sequence is 20 bp.

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.

The T7 gRNA SmartNuclease Cloning and Production Vector in action

Cas9 protein rescues a non-fluorescent eGFP (EGIP), directed by a gRNA synthesized using the T7 gRNA SmartNuclease Cloning and Production Vector.

Figure 1. gRNA cloned-into and synthesized using the T7 gRNA SmartNuclease Cloning and Production Vector directs rescue of a non-fluorescent eGFP mutant using Purified Cas9 Protein. Rescue of non-fluorescent eGFP mutant (EGIP) via homology-directed repair using either a Cas9 All-in-one plasmid system (left panel) or a Cas9 protein-gRNA system (right panel), three days post-transfection. Direct transfection of Cas9 protein-gRNA results in a higher rescue efficiency.
