Overview
Overview
Tag any gene with GFP
Use the PrecisionX™ Gene Tagging HR Targeting Vector (GFP-pA-LoxP-EF1α-RFP-T2A-Hygro-pA-LoxP-MCS) to fuse GFP to any gene in the genome. Clone your homology arms into the two MCSs and use hygromycin selection and RFP-positive imaging to find integrants. After you’ve identified clones with your GFP-tagged gene, 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.

At-a-glance—how to use an HR Targeting Vector to tag a gene
Figure 1. Tagging 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). The tag you’d like to fuse to a gene should lie outside of the two LoxP sites. Result: The HR event leads to insertion of the region of the HR Donor Vector between the two homology arms—your tag ends up fused your gene-of-interest and your selection cassette is integrated. To remove the selection cassette (leaving behind the tag and a single LoxP site), transiently express Cre recombinase.
