![]() ![]() This is achieved by labeling cells with fluorescent markers, such as fluorescent proteins or fluorescently labeled antibodies. Fluorescence, on the other hand, is independent of light scattering and is used to measure specific characteristics of the particles. Visible light scatter is assessed in two directions: forward scatter (FSC), which indicates the relative size of the cell, and side scatter (SSC), which reflects the internal complexity or granularity of the cell. During flow cytometry analysis, each particle is examined for visible light scatter and fluorescence characteristics.Flow cytometry analyzers provide quantifiable data from samples, while cell sorters can physically separate and purify cells of interest based on their optical properties. Some of the common applications of flow cytometry include cell counting, cell sorting, determining cell characteristics and function, detecting microorganisms, biomarker detection, protein engineering detection, diagnosis of health disorders such as blood cancers, and measuring genome size.The technique offers versatility and has numerous applications in different fields, including basic research, clinical practice, and clinical trials. Although flow cytometry is commonly associated with the analysis of cells, it can also be applied to chromosomes, molecules, or other suspended particles in a fluid.By using laser scattering, the flow cytometer can measure the size, internal complexity or granularity, and fluorescence intensity of the particles. The sample is focused to flow through a laser beam, where the interaction of light with the cells provides valuable information about their properties. The process of flow cytometry involves suspending a sample containing cells or particles in a fluid medium, which is then injected into a flow cytometer instrument.This technique has gained significant popularity in both research and clinical settings due to its ability to rapidly analyze multiple attributes of cells, providing qualitative and quantitative data. Flow cytometry is a powerful technology that utilizes lasers to detect and measure various physical and chemical characteristics of cells or particles in a complex fluid mixture. ![]()
