Molecular Detection for Rapid Food Pathogen Testing and Identification

Assurance® GDS system for food pathogen detection

The Assurance® GDS genetic detection system combines the latest advancements in molecular detection technology and food microbiology to provide faster results with the increased accuracy required to meet today’s food and environmental testing challenges. The Assurance® GDS system comprises three simple steps: Sample enrichment, Sample preparation assays utilizing our innovative GDS PickPen® immunomagnetic separation (IMS) device, and PCR analysis with the GDS Rotor-Gene® thermal cycler.

The Assurance® GDS system comprises three simple steps

Test for key foodborne pathogens, including Salmonella, Listeria spp., Listeria monocytogenes, Cronobacter, E. coli O157:H7 (EHEC), and Shiga toxin-producing E. coli (STEC) with confidence.

We offer multiple formats, including options that can be fully automated using the Assurance® GDS PickPen® PipetMax® (PPMX) system

Fast and accurate pathogen detection with the Assurance® GDS system

Simplicity

From start to finish, the Assurance® GDS system is designed to be simple, flexible and easy to run.

  • No centrifuge or heating block required
  • Eliminates associated steps and waiting periods
  • Not dependent on frequently ambiguous melt curve analysis after amplification to determine results
  • Multiplex platform allows for the simultaneous detection of multiple targets within each amplification tube
  • mEHEC® media, a fast proprietary enrichment, has been harmonized for use with Salmonella, EHEC, and STEC assays, for results in as little as 8 hours

Speed

Faster than many conventional thermal cyclers, the Assurance® GDS Rotor-Gene® instrument is an innovative centrifugal air-exchange thermal cycler that puts a new spin on things.

  • Its constant rotary motion overcomes the heat equilibrium issues inherent in conventional Peltier block systems and lowers dwell time, resulting in faster results
  • Save over 2 hours of amplification time per run

Specificity

Patented primers and probes ensure greater accuracy.

Each amplification tube contains a set of highly specific patented primers(probes) and a discrete internal control which ensures the highest level of specificity

  • Minimizes potential for cross-reactivity with non-target organisms
  • Fewer indeterminate or false positive reactions
  • Greater confidence in results
  • Three levels of specificity give reliable pathogen identification

Innovative

The latest innovations in genetic detection technology and food microbiology for rapid accurate detection method.

  • Our proprietary magnetic particles capture the target organism from the enriched sample
  • The innovative Assurance® GDS PickPen® concentration device quickly and easily collects and transfers the concentrated target—8 samples at a time
  • The sample preparation procedure is practical, efficient and simple to run

Sensitivity

Assurance® GDS delivers a greater amount of quality DNA for analysis, ensuring a higher degree of sensitivity.

  • Its innovative patent-pending sample preparation procedure utilizes proprietary magnetic particles to capture and transfer the target organisms from the enriched sample to the amplification tube
  • Concentrated sample makes more DNA available for analysis allowing for a shorter enrichment

Microbiological method validations

Our Assurance® GDS kits have been validated for a range of sample sizes and multiple sample matrices, including Meat, Poultry, Dairy, RTE Meat, Produce, Seafood, Eggs, Infant Formula, Chocolate and Environmental Surfaces.
