flow cytometry principle

The basic principle of flow cytometry is the passage of cells in single file in front of a laser so they can be detected, counted and sorted. Cell components are fluorescently labelled and then excited by the laser to emit light at varying wavelengths.

What is flow cytometry used for?

Flow cytometry is a laboratory method used to detect, identify, and count specific cells. This method can also identify particular components within cells. This information is based on physical characteristics and/or markers called antigens on the cell surface or within cells that are unique to that cell type.

What are the three main systems in a flow cytometer?

A flow cytometer is made up of three main systems: fluidics, optics, and electronics.

How does flow cytometry operate to detect cells?

Flow cytometry (FC) is a technique used to detect and measure physical and chemical characteristics of a population of cells or particles. ... The sample is focused to ideally flow one cell at a time through a laser beam, where the light scattered is characteristic to the cells and their components.

What is the most common clinical application of flow cytometry?

The most common application performed on the cytometer is immunophenotyping. This technique identifies and quantifies populations of cells in a heterogeneous sample - usually blood, bone marrow or lymph.

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.

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.

What does flow cytometry detect?

What is flow cytometry? Flow Cytometry is a technique used to detect and measure physical and chemical characteristics of a population of cells or particles. In this process, a sample containing cells or particles is suspended in a fluid and injected into the flow cytometer instrument.

What does flow cytometry tell us?

Cytometry, in its purest form, is the measurement of cell characteristics, which can include cell size, cell count, cell cycle and more. This technique allows researchers to get highly specific information about individual cells.

Why do a flow cytometry blood test?

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.

Can flow cytometry detect lymphoma?

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

Why is laser light used in flow cytometry?

Lasers are used in flow cytometry as the excitation source of fluorophore-labeled cell samples. Often, multiple laser colors are needed in order to characterize multiple cellular properties.
