Solutions for Plasmid DNA (pDNA) Bioprocessing

Plasmid DNA (pDNA) is a critical raw material delivery template for the development and production of mRNA or viral vectors such as lentivirus and adeno-associated virus (AAV) vectors.

A large segment of viral vectors, critical in gene and cell therapy and other emerging modalities, are generated through transient expression routes based on plasmid DNA (pDNA) as a starting material. Ensuring adequate supplies of pDNA, made at increasingly larger manufacturing scales, is key to the development and delivery of these new therapeutic classes.

Repligen solutions help overcome key challenges in pDNA manufacturing, with hands-on process and implementation consultation from global Field Applications Specialists, and recognized gene therapy, oncolytic and vaccines industry experts.​
