ZFN Service

ZFN Service

As a world-renowned biotechnology company, Baseceuticals provides zinc-finger nuclease (ZFN) service for our global clients, especially those who are currently working on gene therapy field. We build up an excellent and efficient gene editing system based on our advanced techniques and rich experience. We provide customers with one-stop ZFN services, covering from donor design, vector construction, stable cell line generation and target validation. Importantly, we offer high quality and reliable services by enabling any site-specific genome editing without introducing foreign DNA. We will work closely with you to help you move forward your project, achieving gene editing in an efficient and precise way.

Zinc-finger nuclease (ZFN) technology is a prominent tool in the field of genome editing, which is widely used in gene functional analysis, expression manipulation, cellular/animal disease modeling, drug target screening and cell/gene therapies. Zinc-finger nucleases (ZFNs) are a kind of engineered DNA-binding proteins that combine the non-specific cleavage domain (N) of FokI endonuclease with zinc finger protein (ZFP). It can achieve highly specific targeted genome editing by causing double-stranded breaks in DNA at the specific locations. This mechanism depends on the binding of two DNA domains for cleavage, therefore, a strict level of specificity and precision can be achieved. It is reported that ZFN-induced DSBs could be used to modify the genome through either NHEJ or HDR and this technology has subsequently been used to successfully modify genes in human somatic and pluripotent stem cells. For gene therapy, ZFN provides a great method for targeted delivery of the therapeutic genes to a pre-selected chromosomal site to achieve correction.
