Non-Viral Vector Development Platforms

The vector part of the non-viral vector introduction system generally refers to plasmid DNA, or it can also be a vector-free nucleic acid, such as antisense oligonucleotides, ribozyme, siRNA, etc. Our company focuses on common non-viral vectors and their potential future applications, helping our customers to design and develop more novel, highly efficient, and less toxic multifunctional non-viral vectors to further accelerate the progress of gene therapy for rare diseases.

Non-Viral Vectors as Delivery System

Synthetic non-viral vectors offer more modification possibilities to obtain the desired properties of gene delivery systems, including biocompatibility and efficient nucleic acid delivery with high functional activity. Substances that can often be used to construct non-viral vector delivery systems include lipids, polysaccharides, polypeptides or proteins, polyhistidine or polylysine, multivalent cationic compounds, steroids, etc.

Advantages of Non-Viral Vectors

In recent years, non-viral vectors have received increasing attention due to their unique advantages.

  • Non-viral vectors are easy to produce at scale for commercial synthesis and are storage stable.
  • Compared with viral vectors, the toxicity, inflammatory response and off-target effects of the vector are improved.
  • The combination of nanotechnology and nucleic acid-based molecules shows great potential in the field of drug delivery.
