The JRC as Community Reference Laboratory for GM Food and Feed (CRL-GMFF), established by Regulation (EC) No 1829/2003, in collaboration with the European Network of GMO Laboratories (ENGL), has carried out a collaborative study to assess the performance of a quantitative event-specific method to detect and quantify the A5547-127 transformation event in soybean DNA (unique identifier ACS-GMØØ6-4). The collaborative trial was conducted according to internationally accepted guidelines (1, 2).
In accordance with Regulation (EC) No 1829/2003 of 22 September 2003 ¿on genetically modified food and feed¿ and with Regulation (EC) No 641/2004 of 6 April 2004 ¿on detailed rules for the implementation of Regulation (EC) No 1829/2003¿, Bayer CropScience provided the detection method and the samples (genomic DNA from leaves of plants harbouring the A5547-127 event and from leaves of conventional A5547 soybean plants). The JRC prepared the validation samples (calibration samples and blind samples at unknown GM percentage [DNA/DNA]). The collaborative trial involved twelve laboratories from eight European countries.
The results of the international collaborative trial met the ENGL performance requirements. The method is, therefore, considered applicable to the control samples provided, in accordance with the requirements of Annex I-2.C.2 to Commission Regulation (EC) No 641/2004.
The results of the collaborative study are made publicly available at http://gmo-crl.jrc.it/.JRC.DDG.I.4-Molecular biology and genomic
