Enumeration of Viable Cells of Bacteria in Food and Water with Flow ...

WebFlow cytometry (FC) can be used to enumerate viable bacteria in food, beverage, and water samples. The combination of the fluorescent dyes thiazole orange (TO) and propidium iodide (PI) makes it possible to identify cells with membrane damage, investigate cell viability, identify live, dead, and injured cell subpopulations, and enumerate these cells. WebFlow cytometry is used to enumerate CD34+ HPCs to quickly determine the potency of a collected HPC product. However, these cells are rare events which may be masked by nonspecific or interfering populations. Furthermore, various methodologies led to a wide range of recommended CD34 values needed for long-term engraftment. mccormick chamber of commerce sc
