The JRC as Community Reference Laboratory for GM Food and Feed (CRL-GMFF), established by Regulation (EC) No 1829/2003, has carried out an in-house verification study to assess the performance of two quantitative event-specific methods on the maize event MON89034 x MON88017 (unique identifier MON-89Ø34-3 x MON-88Ø17-3) which combines the MON89034 and MON88017 transformation events. The two methods have been validated individually on single-trait events, to detect and quantify each event in maize samples. This study was conducted according to internationally accepted guidelines (1, 2). In accordance to Regulation (EC) No 1829/2003 of 22 September 2003 on genetically modified food and feed and to Regulation (EC) No 641/2004 of 6 April 2004 on detailed rules for the implementation of Regulation (EC) No 1829/2003, Monsanto Company provided the detection methods and the control samples: genomic DNA extracted from seeds of MON89034 x MON88017 maize, genomic DNA extracted from seeds of non-GM maize, seeds of MON89034 x MON88017 and seed of conventional maize. The JRC prepared the in-house verification samples (calibration samples and blind samples at different GM percentages). The results of the in-house verification study were evaluated with reference to ENGL method performance requirements (http://gmo-crl.jrc.ec.europa.eu/guidancedocs.htm) and to the validation results on the parental events (http://gmo-crl.jrc.ec.europa.eu/statusofdoss.htm). The results of this CRL-GMFF in-house verification studies are made publicly available at http://gmo-crl.jrc.ec.europa.eu/
