Listeria Right Now™ is the first environmental test for Listeria that offers results in just 1 hour, allowing facilities to seek, investigate and troubleshoot Listeria more quickly than with conventional methods. The method is ideal for verifying sanitation specifically against Listeria onsite for visibly clean surfaces rinsed free of excess sanitizers. The AOAC-approved test allows users to reduce downtime, avoid an enrichment step, and ultimately protect their brand.

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.
