Less than an hour Total Time-To-Result Means Everything Has Changed

Now you can:

  • Conduct environmental monitoring for Listeria without enrichment.
  • Find a potential problem more quickly — fix the issue before it becomes a serious problem — clean and re-test.
  • Conduct investigations in near real-time after positives.
  • Perform vectoring more easily.
  • Be more flexible and proactive with your environmental testing program.

No enrichment with an easy-to-use system means you can conduct Listeria environmental testing without concern for growing pathogens.


ANSR® Listeria Right Now™

Less than an hour? How is this possible?

The ANSR Listeria Right Now system is able to detect very low numbers of Listeria spp., including L. monocytogenes, from environmental samples without enrichment. The system employs an isothermal, amplified nucleic acid-based reaction to target rRNA. Amplification occurs through a polymerization mechanism by a specific endonuclease. Detection occurs in real-time using a fluorescent molecular beacon.

Ribosomal RNA is present in much greater numbers in Listeria cells than the traditional DNA target (~1000 – 10,000 copies per cell vs. 1 copy per cell for DNA). This can result in a 1,000 – 10,000 fold increase in target analyte concentration.

The isothermal reaction within the instrument produces a constant cycle of molecular replication producing analyte copies much more quickly than traditional PCR reactions which run through a series of heating and cooling cycles.

Summary: Exponentially more targets with a significantly faster cycle time = equals results Right Now.
