TALEN (Transcription Activator-Like Effector Nucleases) gene editing services offer a precise and efficient method for targeted genome modification. TALEN technology utilizes customizable DNA-binding proteins to introduce double-strand breaks at specific genomic locations, enabling precise gene editing. This technique is particularly valuable for applications where high specificity and reduced off-target effects are crucial. Our TALEN gene editing services provide comprehensive solutions for designing, constructing, and validating genetically modified cell lines and organisms tailored to your specific research needs.

Overview Service Process Examples and Solutions Applications Frequently Asked Questions


TALENs are engineered nucleases that combine a DNA-binding domain derived from transcription activator-like effectors (TALEs) with a nuclease domain. By designing TALEs to bind to specific DNA sequences, TALENs can introduce double-strand breaks at targeted sites in the genome. The cell's natural repair mechanisms then facilitate the desired genetic modifications through non-homologous end joining (NHEJ) or homology-directed repair (HDR). This technology enables precise gene knockouts, knock-ins, and other genomic alterations.

Service Process

The process of TALEN gene editing involves several critical and interrelated steps:

  1. Target Identification: Selecting the specific genomic locus for editing based on the research objective or therapeutic goal. Accurate target identification is crucial for the success of the gene editing process.
  2. TALEN Design: Designing TALENs that bind to the target DNA sequence. This involves customizing the TALE domains to recognize specific DNA sequences flanking the target site.
  3. Vector Construction: Cloning the TALEN constructs into appropriate vectors for delivery into the target cells. This step ensures efficient expression of the TALENs in the cells.
  4. Delivery of Editing Components: Introducing the TALEN constructs into the target cells using methods such as electroporation, viral vectors, or lipid nanoparticles. Efficient delivery is vital for successful gene editing.
  5. Selection and Expansion: Isolating and expanding the successfully edited cells. This selection process may involve the use of selectable markers or advanced sorting techniques to enrich the population of edited cells.
  6. Validation: Confirming the presence and accuracy of the genetic modifications through sequencing and functional assays. This step ensures that the edits are precise and that the cells exhibit the expected phenotypic changes.
