GeneQuence Listeria Monocytogenes

Item No.  6708

1. 24 and 48-hour enrichment protocols for food and environmental samples

2. Tests can be performed manually or automated

Intended Use GeneQuence for Listeria provides for the detection  of Listeria in food and environmental samples.  

The Test

This DNA hybridization test employs Listeria spp.-specific DNA probes directly labeled with HRP, and a colorimetric endpoint to detect as little as 1 cfu of Listeria in a 25 g food sample when the specified enrichment protocols are used. A sample is considered negative for the presence of Listeria if the absorbance value (A450) obtained is less than 0.10. A sample is considered positive for the presence of Listeria if the absorbance value obtained is greater than or equal to 0.10. Positive samples should be confirmed by standard culture procedures, followed by biochemical identification.
