Our HybriScan® assays provides fast and accurate molecular detection of spoilage organisms and pathogens, without the need to use expensive PCR methods. HybriScan® Molecular Screening System is suitable for the safety and quality control of beverages, water, and food. - [Rapid Microbiological Method: Sandwich Hybridization](https://www.sigmaaldrich.com#rapid) - [Sensitivity, Specificity and Flexibility of Sandwich Hybridization](https://www.sigmaaldrich.com#sandwich) - [Advantages Of HybriScan® Technology Over Other Microbial Detection Techniques](https://www.sigmaaldrich.com#advantages) - [HybriScan® Wastewater Bacterial Count Calculator](https://www.sigmaaldrich.com#wastewater) - [HybriScan®D (Detection) Kits](https://www.sigmaaldrich.com#kits) - [HybriScan®I (Identification) Kits](https://www.sigmaaldrich.com#identification) [Speak to a specialist](https://www.sigmaaldrich.com/CZ/en/campaigns/microbial-identification-tests) ## [](https://www.sigmaaldrich.com)Rapid Microbiological Method: Sandwich Hybridization The HybriScan® system is based on the detection of microbe-specific rRNA using sandwich hybridization. The method simply needs a centrifuge, a thermal mixer, and an optional microplate reader. The complete analysis can be achieved in 2 hours for the HybriScan®*D* kit (quantitative kits) and about 1 hour for the HybriScan®*I* kit (identification kits). Qualitative results can be determined by eye or, for quantitative measurement, used with a microplate reader. ![HybriScan® system screening workflow includes pre-cultivation of the sample in enrichment broth. After centrifugation, the sample is incubated, immobilized, purified, and finally detected with a read out available in less than 10 min. The total analysis time takes up to 2–2.5 hours.](https://www.sigmaaldrich.com/content/dam/cms-commons/sigmaaldrich/marketing/global/images/technical-documents/articles/microbiological-testing/pathogen-and-spoilage-testing/hybriscan-rapid-molecular-detection-system-workflow.jpg "HybriScan® Rapid Molecular Detection System Workflow") __Figure 1.__HybriScan® system screening workflow with an analysis time of approx. 2–2.5 hours.

Sandwich hybridization provides sensitivity in crude biological samples because it is not susceptible to matrix interference. By using specific probes, the HybriScan® system allows both genus or species-specific detection and it is therefore applicable to many analytical fields, including monitoring the microbial content of beer, wine, non-alcoholic beverages, drinking water, a wide variety of foods and wastewater. ![HybriScan®kits for detection and identification of microorganisms](https://www.sigmaaldrich.com/content/dam/cms-commons/sigmaaldrich/marketing/global/images/technical-documents/articles/microbiological-testing/pathogen-and-spoilage-testing/hybriscan-molecular-detection-400.jpg "HybriScan®kits for detection and identification of microorganisms") __Figure 2.__HybriScan® technology - Detects viable microorganisms only—minimizes false-positive results from dead bacteria - Not sensitive to sample matrix - Genus- and species-specific detection - Results in just 2 hours after enrichment - Broad application range: beer, wine, non-alcoholic beverages, drinking water, food and wastewater - Can be used to detect non-culturable microbes ### Advantages of HybriScan® technology over other microbial detection techniques Detection TechnologyAdvantageDisadvantage HybriScan® system - Detects only living cells - Minimal interference by sample matrix - High specificity - Low cross-reactivity - Easy handling - Cost-efficient read-out - Quantitative and qualitative - High sample throughput (96-microwell plates) - Detects of non-culturable microbes - No differentiation of serotypes or subspecies - Limited probe design (rRNA target) PCR - High sample throughput - Sensitive - Quantitative - No live/dead cell differentiation - Sensitive to matrix interference (high extraction effort) - Susceptible to polymerase inhibition ELISA - Differentiation of serotypes or subspecies - High sample throughput (96-microwell plates) - Quantitative and qualitative - Low sensitivity - Low specificity, higher cross-reactivity - Slow and expensive assay development Conventional cultivation-based methods - Relatively inexpensive - Simple - Specific - Widely accepted method - Time-consuming (up to 10 days) - No detection of non-culturable microbes - Low sample throughput - Laborious ## [](https://www.sigmaaldrich.com)HybriScan® Wastewater Bacterial Count Calculator For our Wastewater Kits - ([HybriScan®*D* Waste Water Microthrix parvicella](https://www.sigmaaldrich.com/CZ/en/product/SIAL/04447) and [HybriScan®*D* Waste Water Total Bacterial Count](https://www.sigmaaldrich.com/CZ/en/product/sial/78436)), we are providing an excel sheet (below) for calculation of total bacterial count, Microthrix count, and the ratio of Microthrix: Total Bacterial Count. ## HybriScan®*D* (Detection) Kits Litujeme, vyskytla se neočekávaná chyba.
