Food Control™ LFA

Food Control™ LFA

Food Control™ LFA is a PCR-kit for fast and reliable detection of foodborne pathogens via conventional PCR in combination with our reliable Lateral Flow Assay (LFA) evaluation technology.

Detecting bacterial contamination is a key aspect in food microbiology. Consequently, microbiological quality control programs are intensified throughout food chain production in order to minimize the risk of intoxicating consumers. Reliability, speed and robustness of a test system to detect the presence or absence, or even the degree of contamination with pathogens, becomes increasingly important. Food Control™ LFA is a diagnostic system for easy non-quantitative detection of presence or absence of foodborne pathogens in agricultural or food industry via conventional PCR and Lateral Flow Assay (LFA) evaluation technology.

Type of Assay

The assay is based on a one tube amplification with a conventional PCR cycler and a subsequent probe specific hybridization technique. The resulting interpretation is a simple readout of coloured bars on a lateral flow stripe.

Recommended Use / Scope

Can be used in research and industry for detection of pathogenic contamination in food or agricultural products. For research use only! Do not use for clinical diagnostic or testing of patient samples.

The kit is available for the detection of the following microorganisms via conventional PCR:

Sample Requirements

The Food Control™ kits are designed for the PCR based detection of bacterial DNA. Isolated total DNA from potentially contaminated food serves here as starting material, typically after pre-cultivation of the sample growth medium.

Time to result

150 minutes

Required Consumables

PCR reaction tubes, 2.0 ml reaction tubes

Optional: DNA can be extracted from enrichment broth using the DNA extraction kit ExtractNow™ Food Control (Cat. No. 609-1050) or user method.

Required Lab Devices

Racks for reaction tubes, benchtop centrifuge for reaction tubes or PCR plates, vortex, variable microliter pipettes (1 µl – 1000 µl), sterile filter tips, any conventional PCR cycler.

Shelf Life and Storage

Components can be stored at +2 to +8 °C for at least 12 months. After rehydration the reagents must be stored at -18 °C.

Compliance

No, certification in progress.
