Today, Flow Cytometry (FCM) is a standard method for automated rapid cell analysis. Flow Cytometry combines optical and fluorescence detection techniques with dedicated fluidics, electronics, and computer technology. Flow Cytometry allows analysis of 100,000 cells or more in less than one minute. Numerous biochemical and physical cell properties are simultaneously analysed for each single cell. Cytomics and Cell Analysis are key tools in many disciplines of medicine, biology, microbiology, pharmacy, biotechnology, industrial plant breeding, food quality control, and industrial process control. Cell Sorting mechanically separates subgroups of cells for further processing.
