HKOCl-4: a rhodol-based yellow fluorescent probe for the detection of hypochlorous acid in living cells and tissues

Highly sensitive and selective yellow probes, HKOCl-4 and its derivatives, have been developed for detecting endogenous HOCl in cytosol and mitochondria of living cells. In addition, visualization of HOCl production in ischemic stroke model has been achieved with HKOCl-4r.
