Listeria monocytogenes NCTC 11994 Lenticule® discs

Description

• General description: Listeria monocytogenes NCTC 11994 Lenticule® discs are Certified Microorganisms Standards (Certified Microbiological Reference Materials), which can be used as quantitative and qualitative control organisms. They contain colony-forming units (CFUs) in the range of 500-50000 per disc.The technology allows long-term conservation and renders the organisms resistant to temperature changes. They are intended to be used as daily internal quality control organisms. These microorganisms are certified according to ISO/IEC 17025 and produced under reproducible conditions compliant with ISO 17034 using authenticated strains from NCTC. These ready-to-use microbiological controls minimize the need for maintaining control strains in the test laboratory and guarantee the use of an authenticated control culture for every quality control test.Lenticule® discs are prepared from a traceable culture obtained freeze-dried from the National Collection of Type Cultures (NCTC) or National Collection of Pathogenic Fungi (NCPF). They are manufactured by Sigma-Aldrich under license from UK Health Security Agency.
• Application: Listeria monocytogenes NCTC 11994 Lenticule® discs are used as reference strains in routine quality control for food, beverage, water, and environmental testing. Additionally, they are excellent for use in method development and validations, as starter cultures, and for use in research studies and educational purposes.
• Features and Benefits: Ready-to-use at convenient CFU rangesNo dilution requiredQuick rehydration in 10 minutesAt least 16 months of shelf life in a standard -20 °C freezerComplete with a comprehensive certificate of analysisNo maintenance of stock culturesNo recovery time or pre-enrichment step is necessaryRobust, efficient, and reliableEasy-to-useCost-effective
