摘要

对研制的3个含量水平的转基因大豆Mon89788 基体标准物质进行多家实验室的验证研究。研究过程包括转基因大豆中基因组DNA的提取和转基因组分的定量PCR方法确认,标准物质的多家实验室协同实验,以及测量的不确定度评估。多家测定分析结果表明,转基因大豆Mon89788 3种不同外源基因/内源基因含量水平的标准物质参考值和扩展不确定度分别为 0.35%±0.17%,0.61%±0.14%,3.17%±1.70% (k=2)。基体为大豆粉的该标准物质可用于转基因大豆含量的定量检测。

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.
