NICEATM Reference Chemical Lists for Test Method Evaluations

Below are lists of reference chemicals that have been used in studies conducted or sponsored by NICEATM for validation of alternative test methods, or have been recommended by ICCVAM for validation of alternative test methods. Lists are downloadable as both Excel spreadsheets and tab-delimited text files. They are accompanied by links to the ICCVAM Test Method Evaluation Reports or references in the scientific literature in which they were originally published, as well as links to pages on the ICCVAM website on which additional information about the method can be found.

Endocrine Disruptors

Published as Tables 2 and 3 in:
Browne et al. 2015. Screening chemicals for estrogen receptor bioactivity using a computational model. Environ Sci Tech 49(14):8804-8814.

Curated Database of Rodent Uterotrophic Bioactivity

NICEATM compiled data from the peer-reviewed literature for in vivo uterotrophic assays that met six minimum criteria specified by accepted test guidelines. These data have potential utility for developing adverse outcome pathways or models of estrogenic activity, prioritizing chemicals for further testing, or evaluating species-specific responses to chemicals.

Skin Sensitization

Recommended Reference Substances for the Murine Local Lymph Node Assay (LLNA)

Published as Appendix F of Recommended Performance Standards: Murine Local Lymph Node Assay, NIH Document No. 09-7357, 2010


Data from analyses of the LLNA conducted on behalf of ICCVAM by NICEATM are available to interested stakeholders as a reference for developing and evaluating alternative approaches to testing and assessment that replace, reduce, or refine the use of animals for identification of potential skin sensitizers.

Recommended Substances for Optimization or Validation of In Vitro Ocular Toxicity Test Methods

Published as Appendix H in ICCVAM Test Method Evaluation Report, NIH Document No. 07-4517, 2006
