  Properties:
MIR162 mass fraction 1000 g/kg

Remarks:
ERM-BF446b is one of five MIR162 maize seed powder certified reference materials (CRMs) containing different mass fractions of this genetically modified maize. ERM-BF446b has been produced from whole seeds of genetically modified maize supplied by Syngenta Seeds, LLC (Clinton, IL, US). According to the information provided by Syngenta Crop Protection NV/SA (Brussels, BE), the MIR162 maize seeds are hemizygous and the MIR162 maize event was inherited from the female parent. In accordance with Commission Regulation (EC) No 65/2004, the unique identifier code SYN-IR162-4 was assigned to the MIR162 maize event. The CRM is supplied in amber glass vials containing at least 1 g *** For more information see https://crm.jrc.ec.europa.eu/p/ERM-BF446b *** Additional keywords: SYN-IR162-4, MIR 162, GMO event

Intended Use:
ERM-BF446b shall only be used for calibration or quality control of methods for the identification and quantification ofgenetically modified MIR162 maize in food and feed.
