 DNA at specific sequences in unidirectional, irreversible fashion to direct integration of a transgene into the host cell genome, allow for stable, site-specific gene integration. The UltraPorator system includes proprietary hardware and software solutions and potentially represents major advancements over current electroporation devices by significantly reducing the processing time and contamination risk. UltraPorator is designed for rapid and cost-effective manufacturing of UltraCAR-T therapies and has the potential to enable rapid manufacturing of a range of gene and cell therapies beyond UltraCAR-T.

Genetically engineered adenoviruses (a common group of viruses) called adenovectors that are designed to insert genes into cells are an important part of our technology platforms. Our AdenoVerse technology platform is composed of a library of engineered adenovector serotypes that yield greater tissue specificity and target selection as compared to known human Ad5 adenovectors. This includes our gorilla adenovectors, which provide a potential competitive advantage with their large payload capacity, ability for repeat administrations and generation of robust antigen-specific immune responses.

The final component of our approach to precision medicine is our ability to control gene expression and regulation using the RheoSwitch, kill switches, and tissue-specific promoters. The RheoSwitch Therapeutic System, our inducible gene switch system, provides quantitative dose-proportionate regulation of the amount and timing of target protein expression in response to an orally available activator ligand. We have developed kill switches, which allow us to selectively eliminate cell therapies in vivo after their administration, to improve their safety profile. We are developing tissue-specific promoters to only induce gene expression locally in cells or tissues of therapeutic interest.

We have leveraged our proprietary and complementary technology platforms discussed above and our expertise in immunology to develop key therapeutic platforms, including UltraCAR-T and AdenoVerse, to address multiple pathways of complex disorders with significant unmet medical needs and to realize our core promise of precision medicine.

Precigen's Therapeutic Platforms

 AdenoVerse 

Our AdenoVerse platform utilizes a library of proprietary adenovectors for the efficient gene delivery of therapeutic effectors, immunomodulators, and vaccine antigens. We have established proprietary manufacturing cell lines and production methodologies from our AdenoVerse platform, which we believe are scalable for commercial supply. We believe that our proprietary gorilla adenovectors, part of the AdenoVerse technology, have superior performance characteristics as compared to current competition, including standard human adenovirus serotype 5, or Ad5, rare human adenovirus types and other non-human pr
