[4-[4-[3-Oxo-6′-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)spiro[isobenzofuran-1(3H),9′-[9H]xanthen]-3′-yl]-1-piperazinyl]butyl]triphenyl-phosphonium iodide

MitoPY1 has been used as a specific mitochondrial H₂O₂ probe to measure mitochondrial ROS (reactive oxygen species) level.

MiroPY1 is an irreversible and bifunctional dye. It employs a triphenylphosphonium targeting group and a boronate-based molecular switch to specifically respond to H2O2 over competing reactive oxygen species (ROS) in the mitochondria. It does not require transfection. MiroPY1 is photostable and limits false positives.
