Method Reference:

AOAC PTM 011201

Method Description:

Samples are analyzed using the Roka Atlas system which utilizes isothermal amplification and chemiluminescence detection.
Confirmation services also available.

Additional Information:

This is a qualitative enrichment procedure which detects very low levels of the potential food borne pathogen. Note that a percentage of all raw commodities may contain a low level of these organisms.

Benefits: The Roka Atlas used for this test has 3 major improvments:

1. Target Capture - concentrates and purifies target nucleic acids before the amplification process

2. TMA (transcription-mediated amplification) Technology -  produces RNA amplicon rather than DNA amplicon; and allows for 100-1000 copies per cycle thus increasing accuracy.

3. Hybridization Protection Assay – a chemiluminescent reaction with a target-specific probe.
