摘要
Genetically modified (GM) Atlantic salmon, AquAdvantage (AquAd), was the first GM animal approved officially for human consumption. Many countries monitor the use of this product under their GM regulations, but a pragmatic system for AquAd-specific detection is needed. Here, we developed a real-time polymerase chain reaction method with high sensitivity for detection of AquAd in foods. This method showed high specificity for the AquAd transgene and the detection limit was 12.5-25 targeted DNA copies per test reaction. An inter-laboratory study using the method developed demonstrated reproducibility at > 0.1% (w/w) AquAd content.
