HKGreen-4I（Cat No.:I045010）is a highly sensitive and selective fluorescent probe designed for the detection of peroxynitrite (ONOO⁻) in biological systems. Featuring a responsive fluorophore scaffold, HKGreen-4I produces a strong green fluorescence upon reacting with peroxynitrite, enabling real-time imaging in live cells and tissues. Its excellent selectivity over other reactive oxygen and nitrogen species, along with rapid response and low cytotoxicity, make it an effective tool for studying nitrosative stress. HKGreen-4I is widely used in research on inflammation, neurodegeneration, cardiovascular diseases, and other conditions where peroxynitrite plays a pathological role.
