Flow cytometry is a popular technique used to examine the characteristics of cells or particles. It can simultaneously analyse multiple parameters such as relative size, internal complexity, relative fluorescence intensity, etc on the same cell within seconds. Cells are passed through a focused laser beam to produce optical signals including light scattering and fluorescence, which are characteristic to them. There are various technology platforms such as Guava® (Merck Millipore), FACS (Becton Dickinson) and Attune Nxt (Thermo Fisher) that successfully measure physical and chemical properties of cells. Scientists at Aurelia Bioscience are well-experienced at using these platforms for a wide range of cell analysis applications ranging from phenotyping to cell health and viability.
