Genetically Modified Organisms

Agriculturally important plants are often genetically modified by the insertion of DNA material from outside the organism into the plant's DNA sequence, allowing the plant to express novel traits that normally would not appear in nature, such as herbicide or insect resistance. Seed harvested from GMO plants will also contain these modifications and are analyzed by reference and rapid test methods.

GMO reference test methods are polymerase chain reaction (PCR) tests that typically are performed in well-equipped routine test laboratories, such as Romer Labs’ Analytical Service labs. These analyses cover qualitative DNA screening methods as well as highly accurate and specific GMO impurity quantifications, by DNA detection, in various food and feed samples, e.g. bulk grain and finished food samples.

Rapid test methods such as AgraStrip® GMO TraitChek™ strip tests are available on the GMO testing market for quick test results. These Lateral Flow Device (LFD) tests are on-site tests designed for field use but can be applied in laboratories, too. The quick qualitative detection of the GM proteins found in raw food and feed commodities is essential for key decision points within the food and feed supply chain. These strip tests can be analyzed and result in a semiquantitative GMO impurity level found in bulk grain samples in conjunction with an AgraVision Reader.
