HR Targeting Vectors
Whether you’re using CRISPR/Cas9 for gene knock-ins, knock-outs, or edits, SBI’s ready-to-clone HR Targeting Vectors are carefully designed for easier workflows
Taking advantage of the cell’s double-strand break (DSB) repair system, homologous recombination (HR) targeting vectors (also known as HR donor vectors) can increase the efficiency of gene knock-outs, and are essential for gene knock-ins, edits, and fusions. SBI’s HR Targeting Vectors are all that and more, with features that can make it easier to find successful clones, minimize the amount of vector DNA left in the genome, minimize off-target integration, and more.

| *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. |
