The quantification of GM in samples can be performed without the need for certified reference materials (CRMs) using QUIZ (quantitation using informative zeros). In this work we have applied QUIZ to estimate the contents of RoundUp Ready™ soya and MON810 in processed food containing one or both GMs. Results show good agreement between derived values and known input of GM material and compare favourably with quantitative real-time PCR. © 2010 Elsevier Ltd.
