Delivering results for Listeria species in under 26 hours

Veriflow® Listeria species (LS) represents an ultra-sensitive and user-friendly class of diagnostics: DNA Signature Capturing Technology for the detection of Listeria species. With an enrichment time of only 24 hours, Veriflow® LS can be used for the presumptive and qualitative detection of Listeria species from a variety of food and environmental matrices. Combined with our Veriflow® for Listeria monocytogenes test kit, we’re empowering food processors with a suite of tools in the fight against Listeria contamination.

The patented vertical-flow technology allows for the sensitivity of real-time PCR tests, but with the ease of use associated with lateral-flow assays. The result is an effective and rapid system that minimizes sample preparation, speeds time to results, improves testing accuracy, and provides easy-to-interpret data for the end user. Veriflow® LS is the next generation in powerful diagnostic tools to help manufacturers and government regulators keep the global food supply safe.

Veriflow® Listeria species is compatible with:

Environmental SamplingHotdogs MatricesDeli Turkey Meat Matrices

Enrich

After 24 hours non-specialized enrichment, transfer 500 μl sample to provided 1.5 ml tube.

24 Hours
Enrich
Amplify

Amplify

Post enrichment, samples are heated for 10 minutes to inactivate any live bacteria. No additional heating or purification steps are involved with the Veriflow® test system. The sample is transferred into pre-dispensed PCR tubes. The assay utilizes the power of polymerase chain reaction (PCR) to rapidly amplify unique genetic signatures of Listeria, if present.


Pre-programmed thermocyclers enable a one-touch system

Detect

The amplified target is transferred to the sample window of a disposable vertical flow through cassette that develops into a visual signal in only 3 minutes.

Simple and Cost Efficient Deployment at Your Facility

The system is comprised of a small, customized thermocycler, pre-aliquoted PCR reagent tubes, and buffers. The intuitive touch screen interface and 96 sample capacity of the thermocycler accommodates the needs of both low and high volume users.

With Veriflex™ technology, users can even run different tests at the same time maximizing workflow efficiencies.

Post-amplification results are obtained in less than 3 minutes via hand-held disposable cassettes, and results can be tracked, stored, and exported via the Veriflow Reader.

Veriflow is ideally suited for the food and beverage industry-– with a modest capital investment and affordable per-test cost. With single step enrichment and no DNA purification, sample prep is simple, and can be completed by existing staff with minimal training.
