GeneQuence for Listeria

GeneQuence^® for Listeria provides for the detection of Listeria in food and environmental samples.

This DNA hybridisation test employs Listeria spp.-specific DNA probes directly labelled with HRP, and a colourimetric 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.

Features and Benefits

• 24 and 48-hour enrichment protocols for food and environmental samples
• Tests can be performed manually or automated
