GMOs

ANALYSES

GMO analyses are divided in three groups:

  1. In a screening PCR, we search for common, regulatory DNA sequences in GMOs, such as the Cauliflower Mosaic Virus promotor 35S (p-35S), the Agrobacterium tumefaciens nopaline synthase terminator (t-NOS), and the Figwort Mosaic Virus promotor 35S (p-FMV). This is done in combination with a detection of one or more plant species (species-specific PCR).
  2. If one or more of the species-specific DNA targets and/or GMO-screening elements are positive, then qualitative analysis is done to look for the presence of EU-authorised GMOs, depending on the crop that was detected (identification PCR).
  3. Finally, the individually identified GMO events are quantified (quantitative PCR) in order to determine whether or not the sample conforms with the regulations (mandatory labeling treshold of 0.9% GMO per crop for EU authorised events).
