JRC-IRMM has released a series of GMO matrix reference materials for the potato event AM04-1020 (ERM-BF430). The materials consist of five different mass fractions levels of AM04-1020 potato with a nominal value of 0, 10, 40, 100 and 1000 g/kg. Genetically modified AM04-1020 potato is modified related to its starch content and - in accordance with Commission Regulation (EC) No 65/2004 - received the unique identifier code BPS-A1Ø2Ø-5.
ERM-BF430 was prepared according to ISO Guides 34 by mixing gravimetrically dried GM and non-GM potato powder. The resulting GM percentages were confirmed by real-time polymerase chain reaction (PCR) analysis after DNA extraction from the powders. The preparation and certification of ERM-BF430a, ERM-BF430b, ERM-BF430c, ERM-BF430d and ERM-BF430e is described in detail in the certification report.
Legislation in the European Union requires labelling of food and feed products containing more than 0.9 % GMOs, provided the GMO has been authorised in Europe. Consequently, certified reference materials are required for the quality control of GMO measurements carried out by GMO testing laboratories.
