viral-icon-01.png Viral Service


Addgene is now providing viral service to help facilitate scientific research. We know that viral production is a common step after requesting plasmids from Addgene, and by providing this service, we can save you time and help you get results faster.


Lentiviruses are distributed as purified viral particles in solution that are suitable for in vitro use. Volume and minimum titers are listed on each item's material page. Actual titers are reported with each shipment.

AAV are distributed as 100 µL of purified viral particles in solution that are suitable for in vivo use. Minimum titers are listed on each item's material page. Actual titers are reported with each shipment.

Virus associated DNA

Each viral service request will also include virus associated DNA, which is a sample of the purified DNA from the original plasmid that was used to make the virus. In order for Addgene to provide viral services to you, we must ensure that you have the right to use the original plasmid.

Distribution of the original plasmid is important because it is the actual material being referenced in the Material Transfer Agreement (MTA) and its inclusion is what gives you permission to use the plasmid.
