ZFN-based Glycogene Editing Technology

ZFN-based Glycogene Editing Technology

Applications of Zinc-finger Nuclease (ZFN)

ZFN is a kind of artificially synthesized restriction endonuclease, which consists of a nonspecific cleavage domain of the Flavobacterium okeanokoites-derived FokI and a DNA-binding zinc-finger domain. At present, in many species such as plants, fruit flies, zebrafish, frogs, moose, and cattle, ZFN technology has been widely used to locate gene variations and new species with genetic backgrounds can be generated through artificial genome information. It is also of great value in the medical field, has potential significance for gene therapy of diseases, and has very broad application prospects.

ZFN-based Glycogene Editing Technology at CD BioGlyco

Gene editing is an emerging genetic engineering technology that more accurately modifies specific target genes in the genome of an organism. The gene editing tool is a sequence-specific endonuclease composed of a sequence-specific DNA binding domain and a non-specific DNA modification domain. The gene editing process is summarized as one search, two cuts, and three repairs. Identify DNA target sites on chromosomes (find), cut and generate DNA double-strand breaks (shear), and induce DNA damage repair (repair), thereby achieving directional editing of the specified genome. Simply put, gene editing is to use of a modified protein as a tool to carry out targeted modification of a specified gene.

  • ZFN-mediated knockout of a glycogene
  • ZFN-mediated knock-in of a glycogene
  • Xenotransplantation
  • Analysis
    • Reverse transcription polymerase chain reaction (RT-PCR)
    • Western blotting
    • Cells culture and proliferation assays, and SA-β-galactosidase assay
    • Non-homologous end joining (NHEJ) assay
    • Homologous recombination (HR) assay
    • Immunofluorescence and fluorescence-activated cell-sorting analysis
    • Mass spectrometry
    • RNA transcriptomic analysis
    • Bioinformatic analysis
  • Targeted knock-in and Delivery Gene Editing

We utilize ZFNs to create complementary DNA overhangs (sticky ends) in both the genomic target site and the donor DNA allowing its integration.
