Aromatase Assay Peer Review Materials

EPA announced in a July 2007 Federal Register Notice (PDF) (4 pp, 67K, About PDF) the approach it intends to take for conducting peer reviews of the Tier 1 screening assays and Tier 2 testing assays that are being validated.  As described in the Federal Register Notice, peer review materials will be posted as they become available. Materials may include the documents to be peer reviewed, background documents, the charge to the peer reviewers, and reports that summarize the results of peer reviews. Peer review materials for the Aromatase Assay can be accessed below:

You will need the free Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more. If you need help accessing these PDF documents, please contact William Wooge at 202-564-8476 or wooge.william@epa.gov for assistance.
