Aldevron announces ready-to-use helper plasmid for AAV manufacturing

New plasmid to reduce cost and timeline for gene therapy manufacturing

Aldevron, the world’s leading contract plasmid manufacturing organization, has announced the immediate availability of an off-the-shelf version of pXX6-80, a common adeno-associated virus (AAV) helper plasmid. The plasmid is designed to reduce the cost of AAV manufacturing and subsequent gene therapy applications, while helping Aldevron’s clients meet regulatory requirements.

pALD-X80-AdobeStock_37326707-small.jpgAAV manufacturing has traditionally required unique custom batches of helper plasmids. This can be expensive and time consuming. Also, older helper plasmid versions often contain antibiotic sequences that are increasingly unacceptable by regulatory agencies. Aldevron’s new pALD-X80 solves these problems by being immediately and universally available with acceptable plasmid elements.

“Gene therapy has experienced tremendous growth over the last year with the approval of multiple products that dramatically improve life,” said Michael Chambers, Aldevron’s CEO. “We are honored to serve this industry and our clients who are achieving these breakthroughs.” Chambers added that the new pALD-X80 is immediately available for research and GMP applications.

AskBio, in its effort to facilitate relief to life threatening diseases, has collaborated with Aldevron to make its critical AAV production reagent available to the entire research community by providing this reagent to Aldevron to make available. AskBio has used Aldevron for all of its clinical GMP production needs and shares in their objective to provide the best reagents at the most effective prices.

The first use of the pXX6 plasmid in recombinant AAV (rAAV) production was published in 1998 (J. Virol. March 1998 vol. 72 no. 3 2224-2232). rAAV is one of the most popular vectors used in gene therapy clinical development worldwide.
