hkocl 4

HKOCl-4 (BXY2142) is a rhodol-based yellow fluorescent probe known for its exceptional sensitivity and selectivity in detecting hypochlorous acid. With an absorption wavelength longer than fluorescein-based probes, it offers improved pH stability. Notably, HKOCl-4 exhibits excitation at 530 nm and emission at 557 nm.

HKOCl-4m is a rhodol-based fluorescent probe designed for the specific and deliberate targeting of mitochondria, enabling the monitoring of mitochondrial hypochlorous acid (HOCl).
