Flow Cytometry: Principles and Clinical Applications

This advanced topic introduces Flow Cytometry and Fluorescence-Activated Cell Sorting (FACS), essential high-throughput analytical techniques for tertiary students in immunology and cell biology in Zambia. It covers the core components of a flow cytometer: fluidics, optics, and electronics, explaining how cells in suspension are interrogated by lasers to measure forward scatter (cell size), side scatter (granularity), and multiple fluorescence parameters. The topic delves into fluorochrome properties, spectral overlap, and compensation, which are critical for accurate data interpretation. It also explores extensive clinical and research applications, including immunophenotyping, intracellular cytokine staining, cell cycle analysis, apoptosis detection, and bead-based multiplex assays (Cytometric Bead Array). For Zambian university and college learners, proficiency in flow cytometry principles is vital for careers in clinical haematology, immunology, cancer research, and advanced diagnostics, providing a powerful tool for single-cell analysis.
