Clostridium botulinum Toxin Gene A/B PCR Kit – screening of enrichment cultures
The Clostridium botulinum Toxin Gene A/B PCR Kit screens enrichment cultures of food samples for the genes of botulinum neurotoxins type A and B. It supports the faster selection of samples for the reference methods.
- Toxin genes type A and B
- For enrichment cultures of food
- 24 tests
How Clostridium botulinum Toxin Gene A/B PCR Kit works
DNA from the enrichment culture is amplified with primers specific for the toxin genes. A positive PCR result shows that the genes are present and is followed up according to the official procedures.
Applications and practical notes
Rapid molecular tests detect clostridia and their toxin genes in enrichment cultures faster than the culture method. Typical applications include:
- Screening of food samples and enrichment cultures
- Investigation of foodborne illness
- Canned and vacuum-packed foods
- Laboratories with PCR or LAMP equipment
Working with Clostridium botulinum Toxin Gene A/B PCR Kit: Treat all positive results as presumptive and forward them to a laboratory authorised for confirmation of botulinum toxin.
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 Clostridium methods: Clostridium perfringens in food and feed is counted according to ISO 7937 on Tryptose Sulfite Cycloserine (TSC) Agar under anaerobic conditions, where sulfite reduction gives black colonies, and ISO 14189 describes the membrane filtration method for water. Sulfite-reducing clostridia are counted on iron sulfite agar according to ISO 15213-1. COLO.Science offers media, supplements, rapid tests and QC strains for these methods.
Complete sets from one supplier: COLO.Science supplies culture media, supplements, rapid tests, identification kits and QC strains as complete sets for the method you follow. Send us your sample types and standards, and we will prepare an offer with the matching products and documentation.
