Flow Cytometry: A Revolution in Cellular Analysis
Flow cytometry has emerged as a cornerstone technology in the field of biomedical research, offering unprecedented insights into cellular characteristics and behavior. This sophisticated technique allows scientists to analyze the physical and chemical properties of individual cells in a fluid stream, enabling a high-throughput, quantitative evaluation that is not achievable through traditional microscopy methods.
At its core, flow cytometry works by suspending cells in a stream of fluid and passing them through a laser beam. As each cell passes through, detectors capture light signals scattered in different directions and fluorescent signals emitted by specific cellular markers. These signals provide detailed information about cell size, granularity, and the presence of particular proteins or molecules. The ability to examine thousands of cells per second makes flow cytometry an invaluable tool for studying complex cell populations with remarkable precision.
One of the most powerful applications of…
