When you think of a "nonprofit" organization what do you think of? Maybe the term brings to mind a social service organization like the Red Cross or the American Cancer Society, or maybe you think about a local food pantry or community arts organization. Many people are surprised to learn that Addgene is officially filed, recognized and operated as a nonprofit under the United States Internal Revenue Code 501(c)(3). That means we were formed to benefit the public, not private interests. On this nonprofit awareness day, we layout the ways in which we promote our mission and work to enable researchers around the world.
