Read this article to learn about the principles of fluorescence. Fluorochromes and Light: Fluorochromes are essentially dyes, which accept light energy (e.g., from a laser) at a given wavelength and re-emit it at a longer wavelength. These two processes are called excitation and emission. The process of emission follows extremely rapidly, commonly in the order of nanoseconds, and is known [...]
Read this article to learn about the principles of flowcytometry. Introduction: The fluorescent antibody techniques described are extremely valuable qualitative tools, but they do not give quantitative data. This shortcoming was remedied by development of the flow cytometer, which was designed to automate the analysis and separation of cells stained with fluorescent antibody. The flow cytometer uses a laser beam [...]
