What is Flow Cytometry?

  • Definition and basics

    Flow cytometry is a powerful and effective laser-based tool for analyzing the structural and functional characteristics of cells or particles in a heterogeneous suspension.

    Flow cytometry, typically using fluorescent probes which bind to specific cell associated molecules, allows measurements of various phenotypic, biochemical and molecular characteristics of individual cells (or particles) suspended in a fluid stream. The flow cytometer consists of a light source, collection optics, electronics and a computer to translate signals to data. The light source of choice is usually a laser which emits coherent light at a specified wavelength. As the cells flow past a focused laser beam of appropriate wavelength, the probes fluoresce and the emitted light is collected and directed to appropriate detectors Scattered and emitted fluorescent light is collected by two lenses (one set in front of the light source and one set at right angles) and by a series of optics, beam splitters and filters, specific bands of fluorescence can be measured (Fig. 1 and Fig. 2).


    Fig 1.


    Fig 2.

  • Advantages

    Speed and analytical power: flow cytometers evaluate cells at an extremely rapid rate (e.g. up to 20,000 events per second) and provide reliable and accurate quantitative analysis of selected physical properties of cells of interest.

    Sensitivity: flow cytometers detect the presence of as few as 50 molecules per cell

    Combinatorial analysis: flow cytometers can rapidly assess individual cells for multiple parameters, including:

    • physical characteristics (cell size, shape and internal complexity)
    • any cell component (extracellular or intracellular) or function that can be detected by a marker attached to a fluorescent compound

    Cell sorting: specifically equipped flow cytometers can also separate (sort) cells of interest from mixed populations for the purpose of further cultivation and analysis.

    One of the properties of the larger flow cytometers is the ability to electronically deflect cells with preset, defined properties into a separate collection tube. Flow cytometry is especially well suited for applications requiring high purity. Cell sorting by flow cytometry can separate complex mixtures of cells on the basis of multiple marker expression.

    Fig.3 Subpopulations of cells or particles that have been resolved by fluorescence or physical parameters can be isolated at up to 99% purity for further experimentation by using the instrument's cell sorting capability. Cell populations can be collected at rates of up to 5,000 cells/second, maintaining sterility to allow for subsequent culturing of the sorted cells. Sorted cells may be collected into tubes (bulk sort) or deposited into multiwell plates using the ACDU. The ACDU is the automatic cell deposition unit and utilizes the CloneCyt software for sorting from 1 up to 100,000 cells per/well. This can be useful for cloning transfected cells, hybridomas, etc. It can also be useful in a preparative manner to sort exact numbers of feeder or co-stimulatory cells into wells. INDEX SORTING allows identification of exact cells from the sort regions that are placed into individual wells. The number of cells that can be sorted depends upon factors such as frequency of events to be sorted, total number, required purity and these can be discussed prior to sorting. Sheath fluid used is sterile PBS unless otherwise instructed, whereupon you will be required to provide the facility with sufficient sheath fluid the day prior to sorting. Temperature control of the sample and collected cells can be set from 4 degrees C up to 37 degrees C.

Applications of flow cytometry

Basic research

Flow cytometry plays an integral role in the understanding of many biological processes: cell cycle and cell growth, cellular DNA and RNA content, cell function and activation, cell differentiation, apoptosis, mitochondrial activity, Ca++ release, hydrogen peroxide production, changes in the plasma membrane potential, intracellular pH etc. Detection of nuclear proteins, oncogenes, and growth factors cytoplasmic enzymes, hormone receptors, and transport proteins Cytometric analysis is not limited to the study of mammalian cells. This technology can also be applied to lower eukaryotes (i.e. yeast) as well as bacteria. Cell cycle kinetics and various aspects of metabolism can be studied. Cells of interest can be sorted and clonally propagated eg for colony assays, generation of cell lines, RNA analysis, FISH, microarrays, PCR and cell micromanipulation.


Flow cytometry is used extensively for immunophenotyping of circulating white blood cells for the purpose of: leukemia and lymphoma characterization, MRD monitoring; determination of T and B cell subset proportions and absolute counts for immune deficiency diagnosis and monitoring; cross-match studies and stem cell content monitoring in transplantology; multi-drug resistance, nuclear ploidy and cell cycle determinations in oncology; reticulocyte and platelets counting, etc.

Applied research

Flow cytometry is a basic tool for development, characterization and standardization of monoclonal antibodies for diagnostic and therapeutic purposes. FCM of microorganisms and other small particles is a promising tool in the fields of aquatic ecology, algal and phytoplankton ecology, food industry, etc.

FCM in Bulgaria: history and current state

The first flow cytometers in Bulgaria started to function in 1987: here, in NCIPD, and in the Laboratory of Immunology of the Medical Academy in Sofia. Twenty years later at least 15 university and private medical laboratories are equipped with flow cytometers for routine diagnostic and monitoring tests.

At the same time numerous research teams, laboratories and institutes engaged in basic research and applied biotechnology are still lacking accessible state-of-the-art cytometry techniques and competent consultation.

    FACS Canto is a fixed-alignment benchtop analyzer. It is approved by FDA and EU for in vitro diagnostics (IVD) and is available basically for clinical cell analysis. This instrument collects information on light scatter (indicating approximate cell size and complexity of interior cell structure) and up to 6 colors of fluorescence emission at a rate of up to several thousand cells per second. Equipped with loader. Post acquisition compensation possible.


    The laser beams are then routed via fiber optics to the beam-shaping prisms where two lasers are projected onto separate spots in the flow cell. Here, the particles intercept with the laser excitation beams and optical signals are collected at the backside of the flow cell with a gel-coupled collection lens. The optical gel, with a refractive index matched to the lens, maximizes the efficiency of light collection. Scattered light and fluorescent signals are then focused onto the emission fiber pinholes. The flow cell is incorporated into the optical plate, creating a solid excitation and collection system with fixed alignment, and no need for user intervention.

Magnetic Cell Sorters

Miltenyi MACS bench-top immunomagnetic cell sorter for cell separations using samples labeled with Miltenyi beads and MACS columns.

Fig.8 MACS® Technology is based on MACS MicroBeads, manual or automated MACS Separators, and MACS Columns. When MACS Columns are placed in a MACS Separator, the MACS Column matrix provides a magnetic field strong enough to retain cells labeled with minimal amounts of magnetic material. Therefore, MACS MicroBeads used for labeling the cells can be so small and only a few are needed to separate a cell. The magnetically labeled cells are separated over a MACS Column placed in a MACS Separator. They are retained on the column, while unlabeled cells pass through. These cells can be collected as the unlabeled fraction. The retained cells are eluted from the MACS Column after removal from the magnet.

Advantages of MACS® Technology:

Gentle to cells: Viable and functionally active cells can be separated in less than 30 minutes. Excellent purity and recovery of both labeled and unlabeled cells.

Flexible separation strategy: Positive selection ,Depletion , Sequential subset sorting (depletion followed by positive selection or MACS MultiSort applications)

Compatible with downstream applications: Flow cytometry, Microscopic analysis, Molecular biology experiments , Cell culture , In vivo experiments

Developed for large-scale cell separations, the SuperMACS™ II Separator allows the separation of more than 1011 total cells in one step. Nonetheless, it can also be used for small cell numbers. Excellent positive selection and depletion rates and the cell friendliness of the separation procedure make the SuperMACS II Separator the ideal tool for research applications in the medical, veterinary, and industrial field. The SuperMACS II Separator is provided with three Column Adapters to insert MACS Columns into the magnetic field. The SuperMACS II Separator can be used with all types of MACS® Separation Columns, except µ Columns and autoMACS™ Columns

Dynall MPC-L bench-top magnetic particle concentrator for cell separations using samples labeled with Dynabeads.

Fig.9 Dynabeads® come in several sizes and with different surface functionalities, for use in a wide variety of applications.

Some beads are pre-coupled with a biomolecule (ligand). The ligand can be an antibody, protein or antigen, DNA/RNA probe or any other molecule with an affinity for the desired target.

  • The magnetic separation protocol consists of three simple steps:
    1. Bind: When added to a sample, Dynabeads® bind to the desired target (cells, pathogenic microorganisms, nucleic acids, peptide, protein or protein complex etc). This interaction relies on the specific affinity of the ligand on the surface of the beads.
    2. Wash: The beads respond to a magnetic field, allowing bound material to be rapidly and efficiently separated from the rest of the sample. Unbound material is simply removed by aspiration, and the bead-bound target washed by the use of the magnet.
    3. Elute: The bead-bound target is released in a suitable volume for use in downstream applications. Alternatively, the bead-bound target can be used directly while still attached to the beads.
  • No centrifugation or columns are required. The protocol is scalable and very automation-friendly.

The Dynal MPC-L Magnetic Particle Concentrator contains a plastic housing and a removable magnet slide incorporating high-energy neodymium magnets. The magnet is designed to hold four separate FACS or Vacutainer tubes (10–16 mm in diameter) with working volumes ranging from 1 ml to 8 ml. It can be used with all Dynabeads but for 1 µm Dynabeads (MyOne™) the volume range is limited to 1-5 ml.
