Who We Are

ATCC is a private, nonprofit biological resource center (BRC) and research organization whose mission focuses on the acquisition, authentication, production, preservation, development and distribution of standard reference microorganisms, cell lines and other materials for research in the life sciences.



ATCC was established in 1925 when a committee of scientists recognized a need for a central collection of microorganisms that would serve scientists all over the world. The early years were spent at the McCormick Institute in Chicago until the organization moved to Georgetown University in Washington, DC in 1937. As research in the biosciences expanded, ATCC began to diversify its holdings, and as the collections grew ATCC occupied a series of sites, each providing more storage space. ATCC moved to its current state-of-the-art building in 1998.



ATCC activities are housed in a Manassas, Virginia facility. The 126,000 sq. ft. building is monitored constantly by on-site security staff, and electric power is backed up by on-site generators. The repository portion of the facility occupies 18,000 sq. ft. and contains 200 freezers to store biomaterials, including vapor-phase liquid nitrogen freezers, mechanical freezers and cold rooms. The repository space is complemented by 35,000 sq. ft. of laboratory space.

The organization holds a collection of more than 3,400 human, animal and plant cell lines. The molecular genomics collection at ATCC contains 8 million cloned genes from a host of species, including human, mouse, soybean, rat, monkey, zebrafish and several disease vectors. ATCC’s microorganism collection includes more than 18,000 strains of bacteria, 2,000 different types of animal viruses and 1,000 plant viruses.
