Abstract Three levels of genetically modified soybeans Mon89788 matrix reference material are developed. Genetically modified soybean genomic DNA extraction and quantitative PCR of transgenic components methods are researched. A multi-laboratory verification and uncertainty evaluation are carried out too.The analysis of multi-laboratory value verification shows that in three different levels of genetically modified soybean Mon89788 reference materials, the transgenic gene / endogenous genes reference value and uncertainty is 0.35%±0.17%,0.61%±0.14%,3.17%±1.70% (k=2), respectively.This set of reference materials that the matrix is soybean grand can be used for the quantitative detection of genetically modified soybeans content.
