Flow Cytometry-based Purification of S. cerevisiae Zygotes

Overview

This study focuses on generating a purified population of yeast zygotes by engineering haploid cells to express fluorescent proteins. The zygotes are isolated using flow cytometry, allowing for further analysis and investigation of zygote morphogenesis.
