Publications
Welcome to our Resources Hub
Find here all our reference documents to better understand our tests, their regulatory context and their applications. Resources mainly designed for R&D, regulatory affairs, toxicology and ecotoxicology teams.
Brochures and technical documents
Our sector-specific brochures give you a clear picture of what Watchfrog tests concretely bring to
your business: regulatory context, endocrine axes covered, and positioning relative to your sector's
requirements.
Our technical documents go further: for each test, you'll find information on the protocol, the
biological principle, result reading criteria and associated scientific references.
Publications (protected access with request form)
Our doctors regularly publish articles in partnership with industry players and other scientists, with
the aim of advancing science as well as regulations at a global level.
A selection of publications is available here upon request.
