mericon Ingredient Authentication Assays are a suite of kits for target-specific authentication of food and animal feed ingredients and certain pharmaceutical product components of animal and plant origin. All of the assays use the same real-time PCR-based protocol. They are part of the comprehensive QIAGEN food testing portfolio, which also features dedicated sample preparation kits, and assays for pathogen and GMO DNA detection. mericon assays perform optimally on the Rotor-Gene Q, but have also been validated for block thermal cyclers.

Principle
Authenticating ingredients using real-time PCR is based on the amplification of a specific region of the relevant target genome. The amplified product is detected using target-specific fluorescent probes that bind to the amplified product. As the PCR product accumulates, there is an increased fluorescent signal from the bound probes. Monitoring the fluorescence intensities during the PCR run (i.e., in real time) allows the detection of the accumulating PCR product without having to re-open the reaction tubes after the PCR run.
mericon PCR Assays include an internal control to control potential inhibiton. This aids in the straightforward interpretation of the results (see the table "Summary of possible PCR outcomes").
The PCR primer set for each assay is highly specific and targets either a genetic construct that is commonly used in GMOs or a DNA sequence that is specific for a particular GMO. These targets were verified bioinformatically and experimentally.

Procedure
DNA is extracted from a sample of food or animal feed using a dedicated sample preparation kit. QIAGEN's DNeasy mericon Food Kit is suitable for a whole range of food matrices, including those with high inhibitor contents.
The isolated, pure DNA is assayed using a streamlined real-time PCR protocol that returns results in 82 minutes on QIAGEN's Rotor-Gene Q. The protocol has also been validated for use on other thermal block cyclers.
The results are displayed as easy-to-interpret PCR curves.
Applications
mericon Ingredient Authentication Assays are for real-time PCR-based detection of DNA segments from specific animal or plant material in food, animal feed, and pharmaceutical products.
