What information does flow cytometry offer?

Flow cytometry (from the greek words cyto = cell and metry = measure) is a powerful technique that can provide us with information about the properties of cells (morphology, cellular properties, cell cycle stage, etc.).

Can flow cytometry detect proteins?

The technique of measuring intracellular protein levels using flow cytometry is a very rapid method to detect protein on a single-cell level. Furthermore, it allows researchers to distinguish the various cell populations in the sample without complicated cell separation, if the appropriate antibodies are used.

What does a flow cytometry test show?

Flow cytometry can identify the type of cells in a blood or bone marrow sample, including the types of cancer cells. It detects types of cancer cells based on either the presence or the absence of certain protein markers (antigens) on a cell’s surface.

What does flow cytometry measure in cells?

Flow cytometry is a cell analysis technique that was first used in the 1950s to measure the volume of cells in a rapidly flowing fluid stream as they passed in front of a viewing aperture.

What kind of data is collected from flow cytometry?

Flow cytometry is a technology that simultaneously measures and then analyzes multiple physical characteristics of single particles, usually cells, as they flow in a fluid stream through a beam of light.

What are the objectives of the flow cytometry experiment?

Flow cytometry is used to determine the physical and chemical properties of cells in a heterogeneous population. Using this method, multiple parameters of single cells can be analyzed simultaneously.

Why is flow cytometry important?

The reason flow cytometry is so successful with heterogeneous cell populations is that it analyzes cells one at a time. It does this by using the properties of fluid dynamics. Flow cytometry data enables the user to understand each cell type and its properties on a deeper level.

What are the principles of flow cytometry?

Flow cytometry (FCM) is a technique which enables rapid analysis of statistically significant number of cells at single cell level. The main principle of this technique is based on scattering of light and emission of fluorescence which occur when a laser beam hits the cells moving in a directed fluid stream.

How do you represent flow cytometry data?

Flow cytometry data is typically represented in one of two ways: histograms, which measure or compare only a single parameter, and dot-plots which compare 2 or 3 parameters simultaneously on a two- or three-dimensional scatter-plot.

What is the role of flow cytometry in protein engineering?

In protein engineering, flow cytometry is used in conjunction with yeast display and bacterial display to identify cell surface-displayed protein variants with desired properties. Bacterial display and sorting can be used for epitope mapping (Rockberg et al., 2008).

How does a flow cytometer measure particles?

Fluidics System One of the fundamentals of flow cytometry is the ability to measure the properties of individual particles . When a sample enters a flow cytometer, the particles are randomly distributed in the 3-D space of the sample line, the diameter of which is significantly larger than the diameter of most cells .

What are antibodies in flow cytometry?

Antibodies are crucial tools for meaningful deconvolution of complex biological samples in flow cytometry as they allow pinpointing specific marker proteins on the cell surface. The more markers you use, the more information on each cell you get; the more antibodies you have the more information you can obtain.

What is a cell sorter in flow cytometry?

A specific type of traditional flow cytometer is the cell sorter which can purify and collect samples for further analysis. A cell sorter allows the user to select (gate) on a population of cells or particles which is positive (or negative) for the desired parameters and then direct those cells into a collection vessel.
