Flow cytometry analysis for A the cell cycle distribution and B Biology Diagrams Cell cycle analysis by quantitation of DNA content was one of the earliest applications of flow cytometry. The DNA of mammalian, yeast, plant or bacterial cells can be stained by a variety of DNA binding dyes. The premise of these dyes is that they are stoichiometric, i.e. they bind in proportion to the amount of DNA present in the cell.

Flow cytometry then allows the simultaneous measurement of incorporated BrdUrd as well as the DNA content on a single cell level. In this way the cohort of labeled cells can be followed through the cell cycle. Figure 2. DNA and cell cycle analysis. An example of DNA and cell cycle analysis.

The ability to analyze thousands of cells per second makes flow cytometry invaluable for research and clinical applications. Phases Of The Cell Cycle. The cell cycle stagesโG0/G1, S, and G2/Mโare crucial for cell growth and division. Flow cytometry is particularly useful in analyzing these phases, offering insights into cellular dynamics. G0/G1
Abstract. In this unit, we describe two protocols for analyzing cell cycle status using flow cytometry. The first is based on the simultaneous analysis of proliferation specific marker (Ki-67) and cellular DNA content, which discriminates resting/quiescent cell populations (G0 cell) and quantifies cell cycle distribution (G1, S or G2/M, respectively).
Analysis of Cell Cycle by Flow Cytometry Biology Diagrams
Cell suspension: Cells must be in a single cell suspension prior to any fixation and staining for cell cycle analysis as aggregates will impact your data interpretation. While both the cytometric and data analysis procedures to evaluate results have mechanisms to exclude aggregates, no method for eliminating them is perfect. The measurement of DNA content as a single parameter is one of the earliest applications of flow cytometry [] and continues to be highly used to this day.It is one of the fundamental techniques in studying cell growth, differentiation, senescence, and apoptosis [].The first reported DNA content analysis method, the Feulgen-DNA staining method, was first reported in 1969 []. The most common application of flow cytometry includes but not limited to cell sorting, immunophenotyping, detection of intracellular molecules, measurement of apoptotic cells, and analysis of cell cycle . In this chapter, we will explain how to analyze the cell cycle using flow cytometry.
