Description
General description
Hypochlorous acid (HOCl) is a highly potent reactive oxygen species (ROS) and helps eliminate pathogens in the innate immune system. Mounting evidence indicates that intracellular HOCl plays additional important roles in regulating inflammation and cellular apoptosis. Subcellular detection of HOCL is currently limited due to low concentration, strong oxidization, and short lifespan of the analyte.
The BioTracker TP-HOCL1 dye is a live cell two-photon green fluorescent “turn-on” imaging probe for HOCL. The probe exhibit fast response times, good selectivity, and high sensitivity towards hypochlorous acid in living cells. Acedan was chosen as the fluorescence reporting group due to its excellent photophysical properties resulting from the typical “push−pull” (amineketone) structure. 2- mercaptoethanol and 1, 2-ethanedithiol were employed to protect the ketone of acedan in the design of HOCl probes. Reaction of the probe with HOCl, which deprotects the oxathiolane/mercaptal group to reveal the ketone, would lead to fluorescence enhancement
