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 is cytometry data?
Data analysis in flowcytometry 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 are flowcytometry results reported?
The official flowcytometry laboratory report is most commonly an individual-lab-generated, paper report form. A discussion of the potential benefits that might result from the development of improved computerized reporting software and from the increased use of antibody-defined, lineage gating is offered.
What is the flow cell in flow cytometry?
A flow cytometer has five main components: a flow cell, a measuring system, a detector, an amplification system, and a computer for analysis of the signals. The flow cell has a liquid stream (sheath fluid), which carries and aligns the cells so that they pass single file through the light beam for sensing.
What does flowcytometry tell us?
Flow cytometry provides a well-established method to identify cells in solution and is most commonly used for evaluating peripheral blood, bone marrow, and other body fluids. Flow cytometry studies are used to identify and quantify immune cells and characterize hematological malignancies.
What do my flowcytometry results mean?
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 a flowcytometry show?
Flow cytometry is a laser-based technique used to detect and analyze the chemical and physical characteristics of cells or particles. It is most commonly used to evaluate bone marrow, peripheral blood and other fluids in your body.
What can you learn from flow cytometry?
Flow cytometry assays information Learn about assays and techniques for detecting and monitoring cell health and function by flow cytometry. Topics include apoptosis, cell counting, proliferation and viability as well as cell cycle, endocytosis, oxidative stress and more.
What is the purpose of flow cytometry?
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.
How do you represent flowcytometry 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.
How does flowcytometry 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.
How do I know if my flowcytometry data is bad?
- Experiment lacks single stain controls.
- Only compensation beads run for single stained controls (no single stained cells).
- Use of isotype controls instead of FMOs.
- Unlabeled parameters and/or tubes.
What is flowcytometry for dummies?
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 applications of flow cytometry?
It has broad application in medicine especially in transplantation, hematology, tumor immunology and chemotherapy, prenatal diagnosis, genetics and sperm sorting for sex preselection. Flow cytometry is widely applied to detect sperm cells abnormality associated with DNA fragmentation in male fertility assays.
What are some clinical applications of flow cytometry?
Clinical application Common characteristic measured

Leukemia and lymphoma phenotyping Leukocyte surface antigens
Identification of prognostically important subgroups TdT, MPO
Hematopoietic progenitor cell enumeration CD34
Diagnosis of systemic mastocytosis CD25, CD69
What information does flowcytometry provide?
Flow cytometry provides a well-established method to identify cells in solution and is most commonly used for evaluating peripheral blood, bone marrow, and other body fluids. Flow cytometry studies are used to identify and quantify immune cells and characterize hematological malignancies. They can measure: cell size.
How is flowcytometry collected?
Collect sample in a conical tube or capped sterile specimen container. Specimens must be submitted in RPMI or Hank's solution. Specimens may also be placed in saline or a saline soaked gauze if to be transported to the Flow lab within 1 hour.
What parameters are collected in flow cytometry?
In a FACS Experiment: Forward-scatter, side-scatter, and fluorescent data is collected, as in conventional flow cytometry. User-defined parameters provide information on how cells should be sorted. Based on these parameters, the FACS machine uses an electrode to impose an electrical charge on each cell.
