Lab Stains and Dyes

Propidium iodide (PI) is a red-fluorescent cell viability dye which is excluded from live cells as it is impermeable to the cell membrane. The dye intercalates DNA and RNA of the dead cells to give red fluorescent signal as it can penetrate dead or damaged cells to give red fluorescent signal. The...
