Lucigenin (NSC-151912) is a chemiluminescent probe used to detect endogenously produced superoxide anion radicals (O₂⁻) in biological systems. After being reduced by a single electron within the cell, lucigenin reacts with superoxide anions to produce measurable chemiluminescence, with excitation/emission wavelengths of Ex/Em=455/505nm[1]. Lucigenin can be used to measure intracellular oxidative stress levels and to study physiological and pathological processes associated with superoxide anions[2].
