Flow cytometry Expertise and services

Flow cytometry is a sophisticated technique that allows interrogation of few to millions of single cells or. Multiple physical characteristics of each individual cell/particle are simultaneously measured, and expression levels of antigens can be detected using fluorescently labelled antibodies. Measured characteristics include amongst others the relative size, granularity or internal complexity, and relative fluorescence intensity of the cell/particle. Our platform offers scientists advice on pre-analysis sample preparation, panel design, quality controls, instrument set-up, data acquisition and data analysis and visualization. Furthermore, we provide access to high-end flow cytometry analyzers and sorters.

What is flow cytometry?


Flow cytometry is a sophisticated technique of single cell analysis. It simultaneously measures and analyzes multiple physical characteristics of single particles, usually cells, as they flow in a fluid stream through a beam of light. Some of the characteristics measured include a particle's relative size, granularity or internal complexity and relative fluorescence intensity.

  • A flow cytometer is composed of three main systems: fluidics, optics and electronics. The fluidics transports the particles in a stream to the laser beam for interrogation. The optics consists of lasers to illuminate the particles in the sample stream and optical filters to direct the resulting light signals to the appropriate detectors. The electronics convert the detected light signals into digital signals that can be processed by the computer.

    Monoclonal antibodies tagged with a fluorescent dye can be used to identify a particular cell type based on individual surface, cytoplasmic, or nuclear antigens. Different mixtures of fluorochromes can be used to distinguish sub-populations. Dyes, which bind directly to cell components such as DNA and RNA, are used as well.

    The flow technology provides a powerful and sensitive tool for investigating the structure and function of cells, bacteria and other particles. These measurements can be made at flow rates of 100-20.000 cells per second.
