The Assurance GDS system offers me a new way to conduct my molecular biology assays, allowing me to analyze even the most complicated matrices like sauces and chocolates. This is thanks to the 'magnetic pipette,' which picks up the metallic beads where the microorganisms are located. It has reduced my costs by avoiding additional confirmation runs or repetitions due to indeterminate results. I highly recommend this equipment.

The Assurance® GDS system is a proven molecular platform comprising three simple steps: sample enrichment, sample preparation assays, and PCR analysis with the Assurance® GDS Rotor-Gene®. Designed for optimum flexibility, various portions of the Assurance® GDS sample preparation can now be automated allowing industrial and plant laboratories to customize their testing to better fit their changing needs.
Assurance® GDS utilizes proprietary magnetic particles and a unique concentration device (Assurance® GDS PickPen™) to capture target pathogens from an enriched sample, separating the target from inhibitory background materials and ensuring valid PCR reactions for all sample matrices. While other molecular methods rely on sensitivity compromising dilution protocols to prevent failed reactions, PickPen™ IMS technology improves assay sensitivity and detection by concentrating pathogens, removing the risk associated with matrix variability and increasing user confidence in test results.
Results are available same day or next day, instead of following a multi-day full cultural confirmation, saving precious time for perishable samples. The Assurance® GDS pathogen detection system includes assays for Salmonella, Salmonella HET, E. coli O157:H7, Shiga Toxigenic E. coli (STEC), Shiga Toxin Genes, Listeria spp., Listeria monocytogenes, and Cronobacter. The system has been validated by a variety of third parties including AOAC, AFNOR, MicroVal, and Health Canada.
Key Features:
- Three levels of specificity: PickPen™ IMS system, primers, and gene probes
- Flexibility: assays can be automated or used manually
- User-friendly: simple sample preparation and LIMS compatible software
- Same-day results: no further interpretation necessary
