Unlock the potential of plasmid DNA across multiple therapeutic approaches, from gene and cell therapies, viral vector production, and immunotherapeutics to mRNA/DNA vaccines and nucleic acid drugs. PackGene provides plasmid preparation services that are ideal for any phase of the drug development cycle including basic discovery research through commercialization at any scale.
Flexible Sizing
We offer production sizes from 100µg to 2g for preclinical grades of plasmid and up to 100g for GMP plasmid production.
Precision
Speed
Wide Compatibility
We offer plasmid production grades that are ideal for all drug development stages, from discovery research to commercialization at any scale. Choose from two plasmid grades for discovery and preclinical work. For clinical stage work, please see GMP plasmid manufacturing
Tailored QC Tests
Our range of quality control tests for endotoxin levels, supercoil content, residual contaminants, and sequence fidelity can be customized for your workflow.
Support for Various Projects
Our plasmids help enable cell transfection, protein expression, AAV packaging, mRNA production, viral vector production, vaccine development, antibody production, and other preclinical processes.
