Analyzing Schizosaccharomyces pombe DNA Content by Flow Cytometry

Area of Science:

• Cell Biology
• Biotechnology

Background:

• Flow cytometry is a key technique for analyzing DNA content and cell cycle progression.
• Fission yeast typically exhibits a single major peak in DNA histograms under standard conditions, representing G1 and G2 phases.

Purpose of the Study:

• To detail a protocol for preparing and analyzing fission yeast cells using flow cytometry.
• To enable discrimination of cells in M/G1, S, and G2 phases through advanced signal analysis.
• To introduce barcoding for improved inter-sample comparison accuracy.

Main Methods:

• Cell preparation for flow cytometry.
• DNA content measurement via fluorescence intensity.
• Analysis of fluorescence signal duration to differentiate cell cycle phases.
• Application of barcoding for sample multiplexing.

Main Results:

• Successful discrimination of fission yeast cells in M/G1, S, and G2 phases.
• Demonstration of DNA histograms for cell cycle analysis.
• Validation of barcoding for enhanced sample comparison.

Conclusions:

• The described flow cytometry protocol provides a robust method for cell cycle analysis in fission yeast.
• Advanced signal analysis and barcoding improve the precision and throughput of cell cycle studies.
• This methodology facilitates a deeper understanding of cell cycle regulation and progression.
