Propidium Iodide
Propidium iodide (PI) is a red-fluorescent nucleic acid stain used for identifying dead cells in assays like flow cytometry and microscopy. Its fluorescence intensifies upon DNA/RNA binding, shifting its Ex/Em peaks, making it vital for viability studies in both in vitro and in vivo research contexts.
