• Custom TAL Effector Nucleases (TALEN)

    TALENs (Transcription Activator-like Effector Nucleases), a promising new class of designer nucleases, can be designed to bind DNA sequences of interest and to introduce dsDNA breaks.

    TALEN Advantages

    ● Highly customizable: target any gene in any cell

    ● Site/sequence-specific genome editing

    ● Multiple applications: knock-out, knock-in, mutagenesis, gene tagging

    ● TALEN was named "Method of the Year 2011" by Nature Methods

    ● Most competitive price & Fastest Delivery in the industry - $395/construct for Plasmid Clones

    TALENs are suitable for genome engineering both in vitro and in vivo. Research has shown commonly used viral vectors including adenoviruses (AdV), lentiviruses (LV) and adenoassociated viruses (AAV) are effective gene transfer vehicles.

    TALEN has revolutionized the array of genome editing based on its ability to create a site-specific double-stranded DNA break. The break is then subsequently repaired by cellular machinery, through either homology-dependent repairs or non-homologous end joining (NHEJ), creating a deletion mutation or a knock-in site for introducing site-specific DNA sequences of interest. Through this mechanism, TALENs can be programmed to delivery virtually any enzyme to any site and execute gene-editing functions, including gene knockout, knock-in, mutagenesis, gene tagging, and for disease and therapeutics models.
