What is Flow Cytometry Mainly Used For?
Flow cytometry is a powerful analytical tool used in research and clinical laboratories for a variety of applications. It allows for the rapid analysis of physical and chemical characteristics of cells or particles as they flow in a fluid stream through a beam of light. The main uses of flow cytometry include:
Cell Counting
- Accurate and rapid counting of cells in a sample, useful in both research and clinical diagnostics.
Cell Sorting
- Separating cells based on their characteristics into different populations, which can then be collected for further analysis or use.
Cell Characterization
- Determining the expression of cell surface and intracellular molecules, allowing for the identification and classification of cell types within a heterogeneous population.
DNA Analysis
- Measuring DNA content for cell cycle analysis, ploidy determination, and identification of aneuploidies.
Immunophenotyping
- Identifying and quantifying the types of immune cells present in a sample, important for diagnosing and monitoring immune disorders.
Functional Studies
- Assessing cellular functions such as calcium flux, pH changes, and enzyme activity.
Apoptosis and Cell Viability
- Evaluating programmed cell death and the proportion of living, dead, and dying cells within a sample.
