Food processors, laboratories, universities and government agencies in more than 45 countries already rely on 3M™ Molecular Detection System for their pathogen testing results. Now 3M Food Safety announces a next generation of 3M™ Molecular Detection Assays: the 3M™ Molecular Detection Assay 2 – Listeria and 3M™ Molecular Detection Assay 2 – Listeria monocytogenes.

Based on the same combination of advanced technologies 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 shorter 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 faster time-to-result after as little as 24 hours of enrichment.

These assays use a streamlined workflow that is 30% faster than first generation assays, enabled by new lysis chemistry that utilizes proprietary 3M nanotechnology and features a unique color-change indicator for increased control during assay processing. This results in fewer steps for today’s busy pathogen testing laboratories looking to enhance productivity, without compromising accuracy.

For existing customers, the ability to transition from original to new assays has been made seamless. First- and second-generation assays can be run simultaneously using the same robust and compact 3M™ Molecular Detection Instrument, maintaining high efficiency and productivity in the laboratory. In order to use the new assays on their existing instrument, customers simply need to download and install a free software upgrade available at 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,” says 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.”
