Flow cytometric resolution of yeast is affected by enzymatic treatment and culture media
Mei Wang | Feizhen Wu | Zhongkai Gu
Saccharomyces cerevisiae is an important model organism and a typical fungal representative for studies of eukaryotes. The cell cycle of yeast can be analyzed by flow cytometry, and refining the cytometric resolution of the cell cycle with this technique is important. Such refinement is potentially influenced by multiple factors, including enzymatic treatment and variations in the culture media used, although this has been subject to only limited investigation. Here, we examined the effect of different enzymatic pre‐treatments and various media on cytometric resolution. We show that cytometric resolution is significantly altered by both enzymatic conditions and the media used. Culture media with different amino nitrogen concentrations potentially impact the protein content in the yeast cell wall, which may affect the permeability of the cell wall and alter cytometric resolution. The present study provides beneficial technical information about the influence of media and enzymes on the cytometric resolution of the yeast cell cycle and most likely other fungi, which should be considered in future research.
