Flow cytometry is a highly effective method for analysing individual cells that has become widely used in the fields of life sciences and medicine. By utilising flow cytometry, researchers can accurately identify and measure specific cell populations within complex mixtures, as well as assess cell cycle progression, proliferation status, and expression of fluorescent markers. Our course aims to provide a comprehensive understanding of the underlying principles of flow cytometry, while also emphasising practical considerations related to the most frequently used assays. Through a combination of theoretical instruction and hands-on training, students will gain the knowledge and skills necessary to effectively design, execute, and interpret flow cytometry experiments.
