摘要: For transferring the event-specific PCR methods of genetically modified papaya Huanong No.1 to other laboratories, we validated the previous developed PCR assays of Huanong No.1 according to the international standard organization (ISO) guidelines. A total of 11 laboratories participated and returned their test results in this trial. In qualitative PCR assay, the high specificity and limit of detection as low as 0.1% was confirmed. For the quantitative PCR assay, the limit of quantification was as low as 25 copies. The quantitative biases among ten blind samples were within the range between 0.21% and 10.04%. Furthermore, the measurement uncertainty of the quantitative PCR results was calculated within the range between 0.28% and 2.92% for these ten samples. All results demonstrated that the Huanong No.1 qualitative and quantitative PCR assays were creditable and applicable for identification and quantification of GM papaya Huanong No.1 in further routine lab analysis.
