Assurance® GDS Molecular Detection

Assurance® GDS microbial molecular detection system for the food industry

Molecular Detection SystemThe 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 genetic detection system utilizes multiple layers of specificity, including immunomagnetic separation (IMS), highly specific primers, and a patented probe system to ensure highly accurate results. We offer multiple formats, including options that can be fully automated.

Fast and accurate pathogen detection

Rapid accurate detection method features the latest innovations in genetic detection technology and food microbiology.

Three levels of specificity for reliable pathogen identification

Assurance® GDS utilizes three levels of specificity to ensure accurate results. These include highly specific primers, probes and immunomagnetic separation.

PickPen® immunomagnetic separation (IMS)

Sample preparation includes our proprietary PickPen® IMS technology, which isolates the target organism to separate it from the food matrix and media. This removes PCR inhibitors which could interfere with the results, while concentrating the sample for a more sensitive assay.
