The readers detect light signals that result from biological, chemical, biochemical, or physical reactions. Microplate Readers and Reader Accessories. Plate reader with live cell imaging and real-time cytometry Propidium Iodide or PI is a cell-impermeant intercalating agent used in flow cytometry to evaluate cell viability. DNA-staining dyes are commonly used in flow cytometry to measure the DNA content in cell populations and assay for cell cycle state. Propidium Iodide (PI) is a membrane-impermeant DNA binding dye that cannot penetrate viable cells. Because PI is excluded from viable cells, it often used to selectively stain dead cells in a mixed live-dead cell population. plate reader or approximately 100 tests using a flow cytometer.

Propidium iodide (PI) is a popular red-fluorescent nuclear and chromosome counterstain. Since propidium iodide is not permeant to live cells, it is also commonly used to detect dead cells in a population.
