This document discusses flow cytometry and its applications. It begins by listing several common flow cytometers, including the BD FACS Aria III, BD FACS Influx, and BD FACS Calibur. It then provides a brief history of the founders of flow cytometry. The document explains that flow cytometry works by quantifying physical properties of cells like size and complexity using light scattering, and displaying this data in histograms and dot plots. Cells can then be sorted based on these measurements. Applications of flow cytometry mentioned include DNA content analysis, protein expression analysis, immunophenotyping of cells, and sorting cells for research purposes. In closing, it provides several references on flow cytometry principles and clinical applications.
