Welcome to the GMOMETHODS application

GMOMETHODS provides information on EU reference methods for GMO Analysis.

The assays are DNA-based detection methods that have been validated in a collaborative study according to ISO 5725 and/or the International Union of Pure and Applied Chemistry (IUPAC) requirements. In alternative, the assays have been verified by the EURL GMFF for EU legal purposes. Data are retrieved from peer-reviewed journals and final reports of collaborative studies.

The application assists control laboratories in selecting appropriate methods for GMO analysis, supplies core data on the experimental protocol and information on methods performance, ring-trial design, plasmid standards, reference materials and links to published articles or validation reports.


Perform your search by inserting a key word or by selecting a GMO unique identifier.
