Abstract：Seven laboratories are organized to verify the value of three levels genetically modified TC1507 maize matrix reference material.The uncertainties of the multi-laboratories values are evaluated. The cooperative Rt-PCR results show that the values and uncertainties of genetically modified TC1507 maize matrix reference material are 0.41%±0.22%, 1.1%±0.4%, 4.5%±1.2% (k=2), respectively.
