Addgene is a non-profit plasmid repository that facilitates the exchange of genetic material between laboratories by offering plasmids and their associated cloning data to not-for-profit laboratories around the world.
Addgene provides a free online database of plasmid cloning information and references, including lists of commonly used vector backbones, popular lentiviral plasmids and molecular cloning protocols.
Addgene was founded in 2004, by Melina Fan, Kenneth Fan and Benjie Chen. The is based in Massachusetts, United States.
Addgene accepts plasmids from researchers for distribution and archival. Addgene obtains revenues and licensing fees using the free depository for commercial sale, and is selective at will in selling acquired depository plasmids to 501 (c) 3 nonprofit organizations at the industrial price for profit gains for its putative non-profit operation.
The organization has partnered with local distributors in China, Japan, and Korea. The organization covers the operating costs of maintaining and improving the collection by charging a nominal fee to scientists requesting plasmids.
