The test is developed for the relative estimation of 35S CaMV promoter DNA amount in only Soya containing products. Therefore the kit contains two PCR systems, one specific for the 35S CaMV promoter sequence and the other one specific for Soya (the reference gene). The detection of the 35S CaMV promoter is according to German Food Law § 64 LFGB.
The real-time PCR assay can be used with established real-time PCR instruments (Roche LightCycler®, Rotor-Gene Q, ABI PRISM, Eppendorf realplex, BioRad CFX96, Agilent MxSeries etc.).
|Test format||2x50 reactions|
|Sample preparation||For DNA-preparation of raw material the use of SureFood® PREP Basic and for highly processed food and feed the use of SureFood® PREP Advanced is recommended.|
|LOD (Detection limit)||The 35S Soya PCR has a limit of detection of < 5 DNA-copies. The assay limit of detection depends on sample matrix, processing grade, DNA-preparation and DNA-content.|
The limit of quantitation depends on the concentration of the sample DNA used in the analysis. For example, if 50,000 target-sequence copies of Soya specific reference gene are present, the relative quantitation limit for 35S Soya DNA is 0.1 %.
