Plasmid Engineering
Precision-Engineered Plasmids to Power Complex Modalities
The success of any gene-modified therapy begins with the correct plasmid. At Minaris, our plasmid engineering services lay the foundation for long-term success by designing and optimizing plasmids for superior transgene expression, expression control, yield and safety.
We collaborate with your R&D team at the earliest stages to create constructs that are fit-for-purpose and scalable, ensuring your therapeutic candidate performs as intended from discovery through IND-enabling studies. We facilitate a smooth transition from research-grade plasmids to scalable GMP manufacturing through our strategic partnerships with specialized plasmid manufacturers.
Comprehensive, Fully Integrated Plasmid Services
Our plasmid technologies are designed to accelerate program development, reduce risk and deliver reproducible performance.
Standard
Off-the-Shelf (OTS) Plasmids
High-quality, research-grade OTS plasmids—including optimized Lentiviral (LVV), Adeno-associated Viral (AAV), and adenovirus systems, as well as the complete SnapFast™ catalog—are available for immediate use from our UK site.
These plasmids enable rapid implementation without the delays of custom vector design.
For clinical applications, clinical-grade plasmids are available through our trusted partners, Aldevron (LVV only) and Bionova (both AAV and LVV), supporting a seamless path from research and development to GMP manufacturing.
