U.; Ernst, B.; Graf, N.; Pietsch, K. Abstract: Validation of a DNA extraction method for use in identification of GMO and derived products is described. Practical LOD (limit of detection) was used as a key tool for assessing suitability of the extraction method for subsequent real-time PCR quantification. In a ring trial (12 laboratories) involving DNA extraction from soy lecithins, satisfactory results with practical LOD of <0.9 % were achieved in 4 of the 5 soy lecithin samples examined. In-house tests showed that this protocol, in a slightly extended version, could also be used to extract DNA from cold pressed rapeseed oils.
