GMO Reference Materials, Qualitative

Some crop types have undergone genetic engineering to impart desirable traits, such as gaining resistance to pests, herbicides, and weather, improving shelf life, and increasing specific nutritional indicators. Because of concerns over the safety of food, forage, and feedstuff produced from GMO plants, their use is strictly regulated in a number of countries. Sigma-Aldrich offers a wide range of certified reference materials (CRMs) for the most widely used GMOs. These products are manufactured by the IRMM (Institute of Reference Materials and Measurements) which is a part of the joint research center (JRC) of the European Commission. Available GMO CRMs include cotton, maize (corn), potato, rapeseed, soya bean, and sugar beet. GMO CRMs are produced gravimetrically, by mixing GMO-containing material with GMO-free material in different ratios to achieve the target level.
