mericon Cattle Kit

For real-time PCR detection of cattle matter in food or animal feed

  • Highly sensitive and specific authentication of ingredients
  • Streamlined protocol
  • Dedicated mericon DNA isolation kit available
  • PCR run time of 82 minutes on the QIAGEN Rotor-Gene Q
  • Full license for PCR without additional costs
The mericon Cattle Kit is designed for the target-specific detection of cattle matter (excluding water buffalo) in food and animal feed ingredients. 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 and GMO DNA detection. The mericon Cattle Kit performs optimally on the Rotor-Gene Q, but has also been validated for block thermal cyclers.

Product Details


The mericon Cattle Kit is for the detection of cattle matter (excluding water buffalo) in food or animal feed. It can detect as few as 10 copies of the target DNA in a reaction and it exhibits high specificity for cattle. No cross-reactivity was observed with other plant or animal species, using 50 ng of the tested DNA (see the table "Results of mericon Cattle Kit cross-reactivity study").

The mericon Cattle Kit is designed for the qualitative detection of cattle matter in food and animal feed. The detection of target DNA confirms ingredient authenticity or prevents food fraud, ethical issues, or health concerns.

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 inhibition. This aids in the straightforward interpretation of the results (see the table "Summary of possible PCR outcomes").

Summary of possible PCR outcomes
Internal control amplified Tested DNA amplified Meaning
            +            +  Sample is positive for the target DNA
            +            –  Sample is negative for the target DNA
            –            –  PCR failed due to inhibition

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.

The mericon Cattle Kit is for real-time PCR-based detection of cattle matter in food and animal feed.
