Nanoplasmid™ Vector Design/Retrofit
The Power of a Small Backbone for Gene & Cell Therapies
Nanoplasmid™ vectors are easily substituted for conventional plasmids, minicircles, Doggybone™ DNA, etc., for use with all major downstream vector technologies. The Nanoplasmid backbone was modified to remove bacterial coding sequences, uses an antibiotic-free selection system, and has profound beneficial effects on performance across a range of gene, cell, and mRNA therapies and vaccines including:
- Higher Transgene Expression and Duration
- Increases Plasmid DNA Manufacturing Yields
- Improves Safety Profile by Eliminating Antibiotic Resistant Gene
- Saves Time and Costs
Nanoplasmid Retrofit & Design Services
Our Nanoplasmid experts will work with you to either design a Nanoplasmid vector from scratch or retrofit an existing, traditional plasmid into a high-performing Nanoplasmid vector alternative, including sequence verification and DNA production. A retrofit entails sending us 10 micrograms of your plasmid (on filter paper or in liquid form). We will swap your current plasmid backbone for the Nanoplasmid version, verify the construct, and return the desired quantity of the amplified product.
Nanoplasmid Manufacturing
Nanoplasmid vectors combine the improved performance of minicircles with the manufacturing attributes of traditional plasmids. Therefore, our custom plasmid DNA manufacturing services are available for both Nanoplasmid vectors and traditional plasmids.

Dr. Tyler Kozisek is a Senior Scientist II in R&D at Aldevron, where he leads the Nanoplasmid design team. With a bachelor's degree in mechanical engineering and a Ph.D. in biomedical engineering from the University of Nebraska–Lincoln, Dr. Kozisek brings a multidisciplinary approach to plasmid engineering. His doctoral research focused on optimizing nonviral gene delivery methods and plasmid design to enhance transfection efficiency in primary human mesenchymal stem cells. Today, he applies that expertise to advance the development of next-generation plasmid technologies, driving innovation in gene therapy and cell engineering. |
Nanoplasmid is a disruptive technology in the clinical and pre-clinical arena. There have been dozens of publications showing off how this small backbone delivers powerful benefits.
