mericon GMO Screen CTP2-CP4EPSPS Kit
For real-time PCR detection of GMOs with the CTP2-CP4EPSPS construct in food or animal feed
The mericon GMO Screen CTP2-CP4EPSPS Kit is designed for the target-specific detection of the CTP2-CP4EPSPS construct in food, animal feed, and pharmaceutical products. The assay uses a real-time PCR-based protocol and forms part of the comprehensive QIAGEN food testing portfolio, which also features dedicated sample preparation kits and assays for pathogen detection and ingredient authentication. The mericon GMO Screen CTP2-CP4EPSPS Kit performs optimally on the Rotor-Gene Q, but has also been validated for block thermal cyclers.

Product Details
Performance
The mericon Screen CTP2-CP4EPSPS Kit is designed for the detection of the CTP2-CP4EPSPS construct in food and animal feed. The mericon Screen CTP2-CP4EPSPS Kit can detect as little as 10 copies of target DNA in a reaction and exhibits high specificity for the construct CTP2-CP4EPSPS. No cross-reactivity was observed with other genetic constructs or with plant or animal species not containing this genetic construct using 50 ng of tested DNA (see the table "Results of mericon GMO Screen CTP2-CP4EPSPS Kit cross-reactivity study").

Principle
The mericon GMO Screen CTP2-CP4EPSPS Kit is designed for the qualitative detection of genetically modified organisms (GMOs) containing the EPSPS gene with an upstream chloroplast-targeting signal (CTP2). The EPSPS protein, active in the chloroplast, confers resistance to the herbicide glyphosate in genetically modified plants. Detection of GMOs using real-time PCR is based on the amplification of a specific region of the relevant GMO genome. The amplified product is detected using target-specific fluorescent probes that bind to it. 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 afterward. mericon PCR Assays include an internal control to control potential inhibition. 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 wide 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
The mericon GMO Screen CTP2-CP4EPSPS Kit is for real-time PCR-based detection of the CTP2-CP4EPSPS construct in food, animal feed, and pharmaceutical products.
