flow cytometry data analysis

Flow cytometry data analysis is built upon the principle of gating. Gates and regions are placed around populations of cells with common characteristics, usually forward scatter, side scatter and marker expression, to investigate and to quantify these populations of interest.

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 flow cytometry an analysis of?

Flow cytometry is a widely used method for analyzing the expression of cell surface and intracellular molecules, characterizing and defining different cell types in a heterogeneous cell population, assessing the purity of isolated subpopulations, and analyzing cell size and volume.

How does the flow cytometer detect events?

Accurate detection of rare-cell events using flow cytometry requires the ability to detect single cells with specific characteristics in a heterogeneous population of cells. ... Poisson statistics apply when counting randomly distributed populations, where precision increases as more events are acquired [1].

Can flow cytometry detect lymphoma?

Flow Cytometry Can Diagnose Classical Hodgkin Lymphoma in Lymph Nodes With High Sensitivity and Specificity.

Can flow cytometry detect leukemia?

Flow cytometry immunophenotyping may be performed on blood, bone marrow, or other samples to provide this additional information. It can detect normal cells as well as abnormal cells whose pattern of markers are typically seen with specific types of leukemia and lymphoma.

Why is flow cytometry important?

Flow cytometry can be used to count and even distinguish cells of different types in a mixture by quantitating their structural features. Therefore, flow cytometry has great advantages compared to traditional microscopy since it permits the analysis of a greater number of cells in a fraction of the time.

How many events do you need for flow cytometry?

It is limited to a frequency of 1 in 100,000 beyond which only rough estimates can be obtained even after collecting 10 7 events.

Is FACS flow cytometry?

FACS is an abbreviation for fluorescence-activated single cell sorting, which is a flow cytometry technique that further adds a degree of functionality. ... The technology to physically sort a heterogeneous mixture of cells into different populations is useful for many therapeutic and clinical applications.

Can flow cytometry detect dead cells?

Loss of membrane integrity is a definitive indicator of cell death in flow cytometric assays. Cells that exclude a dead cell dye are considered viable, while cells with a compromised membrane allow the dye inside into cell to stain an internal component, thus identifying the cell as dead.

Does flow cytometry count dead cells?

Flow Cytometry: Discriminate between live and dead cells

Discriminating between viable (live) and non-viable (dead) cells is important to flow cytometric analysis. Dead cells in your samples can non-specifically bind to your antibodies, resulting in false positives and, ultimately, inaccurate results.

How long do flow cytometry results take?

These patterns are compared to normal patterns to determine the significance of the results. The test takes approximately three hours and consists of staining the cells, acquiring the cells on a flow cytometer, and then having a skilled technologist analyze the results that have been saved to a computer file.
