Overview
Overview
Get precise genomic integration of your expression cassette
Use the PrecisionX™ Gene Knock-out HR Targeting Vector (MCS1-EF1α-RFP-T2A-Puro-pA-MCS2) to knock-out any gene or edit the genome. Clone your homology arms into MCS1 and MCS2, and use puromycin selection and RFP-positive imaging to find integrants. After you’ve identified clones with your gene-of-interest knocked-out or edited, you can remove the selection cassette using the Cre-LoxP system (learn more about Cre-LoxP excision here).
Why use an HR targeting vector?
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.

| *All HR Target Vectors except PBHR100A-1 contain LoxP sites. Any sequences that are integrated between the two LoxP sites can be removed through transient expression of Cre Recombinase. **The clever design of these HR Donors enables enrichment for on-target integration events. A PGK-hsvTK cassette is included outside of the homology arms. Because of this configuration, on-target integration that results from homologous recombination will not include the PGK-hsvTK cassette—only randomly-integrated off-target events will lead to integration of PGK-hsvTK and resulting TK activity. Therefore, TK selection will negatively select against off-target integrants. Click on any one of these vectors to see a diagram of how the negative selection works. |

At-a-glance—how to use an HR Targeting Vector to knock-out a gene
Figure 1. Knocking-out a gene using an HR Targeting Vector. Step 1: Cas9 creates a double-stranded break(DSB) in the genomic DNA at a site that is complimentary to the gRNA. Step 2: The DNA repair machinery is recruited to the DSB. In the presence of an HR Donor with homology to the region adjacent to the DSB (blue areas of the genomic and vector DNA) homologous recombination (HR) is favored over non-homologous end joining (NHEJ). Result: The HR event leads to insertion of the region of the HR Donor Vector between the two homology arms—your selection cassette is integrated into the gene, disrupting the open reading frame.
At-a-glance—how to use an HR Targeting Vector to edit a gene
Figure 2. Editing a gene using an HR Targeting Vector. Step 1: Cas9 creates a double-stranded break (DSB) in the genomic DNA at a site that is complimentary to the gRNA. For gene editing, this DSB should be within an intron. Step 2: The DNA repair machinery is recruited to the DSB. In the presence of an HR Donor with homology to the region adjacent to the DSB (blue areas of the genomic and vector DNA) homologous recombination (HR) is favored over non-homologous end joining (NHEJ). If one of the homology arms of the HR donor contains the gene edit, it will be incorporated into the gene through the HR repair process. Step 3: Transient expression of Cre recombinase will result in excision of the selection cassette, leaving behind a single intronic LoxP site.
