ATCC is the largest biological resource center in the world with the most comprehensive source of reference cultures and reagents. Since 1925, the company has set the standard for authentication and distribution of biological reference materials. An authenticated, genuine culture from ATCC (or an authorized international distributor) is a direct, minimal-passage descendant of the original material deposited with ATCC and has been handled only by ATCC. Our system of maintaining seed stock and distribution stock — with quality control checks throughout the process — ensures this. These products are backed by the ATCC warranty and are covered by our expert technical support. Search the ATCC online catalog, choose an individual product line or search all ATCC collections.
