LGC Standards has announced that a new range of genetically modified (GM) certified reference materials (CRMs) are now available, certified to ISO Guide 34.
Produced by the Institute for Reference Materials and Measurements (IRMM), these CRMs meet the recommendations from the European Commission.
Recommendation (EC) No 787/2004 suggests that results of the content of genetically modified organisms (GMO) in food and feed should be expressed as copy number ratios.
IRMM has released a string of plasmidic DNA materials: ERM-AD413, ERM-AD415, ERM-AD425 and ERM-AD427.
These are intended as calibrants for the determination of GMO copy number ratios for GM varieties authorised in Europe.
In addition to these new plasmidic DNA-certified reference materials, certified values for copy number ratios have been assigned, in addition to the existing certified mass fractions to a selection of existing matrix CRMs to allow laboratories to implement this recommendation.
With the copy number certification (and the matching plasmidic calibrant), LGC Standards and IRMM are supporting analysts wishing to apply the commission recommendation with quality assurance and measurement tools to do so in a controlled manner.
LGC Standards supplies the complete range of GMO-certified reference materials from IRMM, including maize, cotton seed and sugar beet, which can be used as calibrants for DNA-based methods.
