Learn More About Alternatives

AltTox.org is a website dedicated to advancing non-animal methods of toxicity testing, both to better protect the health of humans, animals, and the environment and to reduce the numbers and suffering of animals used in current toxicology assessments. The website is designed to encourage the exchange of technical and policy information on in vitro and in silico methods for all types of toxicity tests. The target audience includes stakeholders in industry, government, academia, and nongovernmental organizations.

Alt Web

Altweb, the Alternatives to Animal Testing Web Site, was created to serve as a gateway to alternatives news, information, and resources on the Internet and beyond. Altweb now is the U.S. home of the journal ALTEX: Alternatives to Animal Experimentation, which is the official publication of the Johns Hopkins Center for Alternatives to Animal Testing (CAAT).


The American Society for Cellular and Computational Toxicology (ASCCT) is a scientific society dedicated to the promotion of toxicology testing and research that reduces and replaces the use of animals.

Toxicology testing is currently undergoing a paradigm shift from a primarily observational, whole animal-based science to a predictive, mode of action-focused discipline.

The Society aims to provide an organized forum for discussion of cellular (in vitro) and computational toxicology approaches especially as replacements for animal-based toxicology methods. Through its meetings and activities, the Society will facilitate the development, acceptance, and routine use of cellular and computational methods through open dialog between industry, academic, advocacy, and regulatory scientists. The Society strives to include the participation of young scientists to promote their contributions to the field.

FCS-free Database

This website provides an overview of Fetal Calf Serum (FCS) and serum-free media for cell culture, and includes a function that allows researchers to find alternatives and discuss the applicability of each product. The FCS-free Database was developed to address moral and scientific concerns associated with serum media, particularly FCS, which is collected from the hearts of fetuses obtained from pregnant cows during slaughter. The Database is offered by the 3Rs-Centre Utrecht Life Sciences in collaboration with Animal Free Research UK.

The Science Bank

The Science Bank, operated by Animalearn, is home to over 650 high-quality, animal-friendly humane science education products. The Science Bank loan program has served thousands of people for over two decades, and has grown to be the largest free loan program of humane science education alternatives in the United States.
