Specific Determination of Viable Cell Count

The Flow VIT® Lactobacillus rhamnosus test kit enables the rapid and precise analysis of Lactobacillus rhamnosus in probiotics. Through the innovative combination of fluorescence in situ hybridisation (FISH) and flow cytometry, this test kit offers cultivation-independent and absolute quantification of living cells within a very short time. Thanks to this advanced technology, the viability and quantity of probiotic bacteria can be determined quickly, automatically and highly specifically, even in complex probiotic mixtures.

Comparison with other technologies

Compared to conventional, cultivation-based methods, Flow VIT® enables faster and more powerful analysis of Lactobacillus rhamnosus. Even non-cultivable but viable cells (VBNC) can be identified and quantified. Compared to other molecular biological methods, Flow VIT® stands out due to its ability to detect only living cells and to reliably quantify them even in complex samples. Since no enzymes are used, the method is extremely robust and reliable. Flow VIT® is a direct method that stains the cells highly specifically and evaluates them directly using automated flow cytometry.



New study in Frontiers in Microbiology: Flow FISH/VIT® overcomes the limitations of traditional methods and enables the simultaneous rapid quantification of different species in a single product. The method has the potential to revolutionize quality control in the field of probiotics.
