Listeria Latex Kit – serological screening of suspect colonies
Latex agglutination kit for the rapid serological screening of suspect Listeria colonies after isolation.
- Slide agglutination with colonies from agar plates
- Result within minutes
- 50 tests per kit · COLO code PRO7901
How the Listeria Latex Kit works
Latex particles coated with antibodies against Listeria antigens are mixed on a slide with material from a suspect colony. Visible agglutination within minutes indicates a positive reaction.
Applications and practical notes
The kit is used in the confirmation step after isolation, complementing the tests in ISO 11290-1. Typical applications include:
- food and feed laboratories
- dairy and cheese laboratories
- environmental monitoring
- teaching laboratories
Working with Listeria Latex Kit: Use colonies from non-selective agar such as TSYEA where possible, and read the slide within the stated time.
Good practice with rapid tests: store the kit as stated on the label, let the components reach room temperature before use and use each item only once. Record the lot number and the result, and confirm positive results according to the reference method when this is required.
About the Salmonella culture method: the reference method for Salmonella in the food chain, ISO 6579-1, has four steps: non-selective pre-enrichment, selective enrichment in two broths, plating on two selective agars and confirmation of typical colonies. The FDA BAM Chapter 5 follows the same principle with media adapted to different food types. Rapid tests and identification kits shorten the time to result, but positive screening results are usually confirmed by the culture method. COLO.Science offers products for every step, so that one supplier covers the whole procedure.
