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. can be counterstained. 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.
Flow Cytometry and Cell Cycle Analysis: An Overview Biology Diagrams
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). 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. Cell cycle analysis is one of the earliest applications in flow cytometry and continues to be highly used to this day. Since the first reported method of Feulgen-DNA staining, cell cycle analysis has continued to grow and mature. With the recent advances in DNA dyes, understanding of additional cell โฆ

Jurkat cells, a human T cell leukemia cell line, were pulsed with 10 ยตM EdU for 2 hours prior to detection with Alexa Fluor 647 azide. 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.
