Flow cytometry dead cells
WebA flow cytometer combines three systems to analyze single cells from a mixture ( 3 ): An optics system. A fluidics system. An electronics system. Cells are first resuspended in a pressurized buffer called sheath fluid … WebCells have to be stored in the cold protected from light and can be analyzed approximately 30 min after the addition of the F/AD solution. Cells are run on the flow cytometer in the F/AD solution. Samples can be stored up to 3 days without any loss in the ability to discriminate dead from live cells. Materials:
