Viral vectors previously available at the University of Pennsylvania Vector Core (Penn Vector Core) are now being distributed through Addgene.
As a non-profit repository, we do not own any of the materials that we distribute, and we have a responsibility to our depositors and any applicable third parties to ensure that these materials are distributed under certain terms and conditions. When ordering materials from Addgene, a new MTA is required even if an order of the same viral vector has been previously fulfilled by the Penn Vector Core.
For more information please visit the MTA Section of our Help Center.
