3M Introduces Next-Generation Assays for Pathogen Detection

Expanding on its molecular detection, 3M Food Safety has introduced a next generation of assays: the 3M Molecular Detection Assay 2 – Listeria and 3M Molecular Detection Assay 2 – Listeria monocytogenes. Based on the same combination of technology used in all 3M Molecular Detection Assays – isothermal DNA amplification and bioluminescence detection – these next-generation assays use new chemistry to deliver accurate results with short enrichment times and improved productivity.

Applicable to environmental samples and a broad range of food types (dairy products, ready-to-eat and raw meats, fish and seafood, fruits and vegetables) and using a standard enrichment medium, the next generation assays for Listeria and Listeria monocytogenes provide a time-to-result after as little as 24 hours of enrichment. These assays use a streamlined workflow enabled by lysis chemistry that utilizes proprietary 3M nanotechnology and features a color-change indicator for increased control during assay processing.

First and second generation assays can be run simultaneously using the 3M Molecular Detection Instrument, maintaining high efficiency and productivity in the laboratory. To use the new assays on their existing instrument, customers simply need to download and install a free software upgrade available at www.3M.com/foodsafety. In addition to making the new assay platform compatible, the software enhancements feature a redesigned user interface and new features that allow for easier, more efficient data entry and improved administrative control.

“The next-generation 3M Molecular Detection Assay 2 tests came to life through ongoing customer engagement and 3M innovation, and we are excited to provide these improvements to our customers while maintaining a fundamental aspect of our original assays – one protocol for all pathogens.” said John David, global marketing supervisor with 3M Food Safety. “The next-generation assays all use a single assay protocol, simplifying our customers’ process and improving their productivity.”
