Molecular and genetic studies of genetically engineered potato: transformation event PH05-026-0048

Expert evaluation of genetically engineered organisms (GMO) identification methods is aimed at confirmation their adequacy with the tool and methodological base used in the institutions of the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing to control market turnover and labelling of genetically engineered food. The primer system's specificity was experimentally confirmed in studies with other GM potato lines, as well as with the results of the BLAST-analysis. The efficiency, linearity and correctness of the method meet the requirements of the European Union Reference Laboratory for GM Food and Feed. Limit of detection and limit of quantification of GM potato line PH05-026-0048 genomic DNA were 0.019% (11 copies of the GM potato genomic DNA) and 0.06% (36 copies of the GM genomic DNA of the potato) per 100 ng of total DNA, respectively.
