Summary
Flow cytometry (FCM) is a powerful cell analysis technique. It rapidly measures multiple cellular characteristics by analyzing light scattering and fluorescence from single cells in a fluid stream.
Area of Science:
- Biotechnology
- Cell Biology
- Analytical Chemistry
Background:
- Flow cytometry (FCM) is an advanced method for analyzing individual cells.
- It enables the simultaneous measurement of numerous cellular properties.
- The technique relies on precise fluid dynamics and optical detection.
Purpose of the Study:
- To explain the fundamental principles of flow cytometry.
- To highlight its capability in analyzing cellular parameters.
- To underscore its speed and multi-parametric analysis.
Main Methods:
- Hydrodynamic focusing of single cells in suspension.
- Interception of the cell stream by an excitation light beam.
- Detection of light scattering and fluorescence signals.
Main Results:
- Each cell generates light scattering and fluorescence signals.
- These signals are proportional to cellular size and internal/external structures.
- Fluorescence intensity correlates with labeled cellular components.
Conclusions:
- Flow cytometry provides rapid, high-throughput analysis of single cells.

01:23Flow Cytometry
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing capillary system. Moldavan pumped cells through a capillary tube focused under a microscope for visualization. The invention of photometry allowed the measurement of differentially-stained cells, and Louis Kamentsky developed the first multiparameter flow cytometer in 1965 to identify and count the cancer cells in cervical tissue specimens.

01:19Protein Dynamics in Living Cells
Different fluorescence-based techniques are used to study the protein dynamics in living cells. These techniques include FRAP, FRET, and PET.
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
