BAX® System PCR Assay

When Listeria is present in a food environmental sample, the genetic-based BAX® system uses the power of the polymerase chain reaction (PCR) to rapidly create (amplify) millions of copies of a unique, Listeria -specific DNA fragment for reliable detection.

BAX® system assays simplify the method by combining all the PCR reagents you need into a single tablet, conveniently packaged inside the PCR tubes contained in each kit. Tableted reagents provide for minimal hands-on time, in addition to accuracy, long shelf life and consistency.

After standard enrichment, samples are lysed to break open the cell walls and release DNA. This lysate is then used to hydrate the PCR tablets. Processing in the automated unit takes less than 4 hours for a full rack of 96 tests. Electronic results appear as positive/negative icons on screen, and the data can be easily stored, shared or printed.

Applications

The BAX® system detects Listeria on a variety of surfaces, including ceramic, plastic, wood, iron, concrete and more.

Proprietary BAX® system Listeria media combines a single enrichment step with shorter incubation times (24 hours for swabs and 28 hours for sponges) for quicker time to result.

Validation studies have shown that the single-enrichment BAX® system performs as well at 24-28 hours as the dual-enrichment USDA-FSIS culture method at 48 hours.

With specificity rate of >99%, the BAX® sytem for detecting Listeria has been certified by AOAC Research Institute as a Performance Tested method. 

Approvals

Samples of this test kit model were independently evaluated by the AOAC Research Institute and were found to perform tothe producer's specifications as stated in the test kit's descriptive insert. The producer certifies this kit conforms in all respects to the specifications originally evaluated by the AOAC Research Institute as detailed in the Performance Tested Certificate number 030502
