Product Description
Liperfluo, a perylene derivative containing oligooxyethylene, is designed and exclusively developed by Dojindo for a detection of lipid peroxides and emits intense fluorescence by a lipid peroxide specific oxidation in organic solvents such as ethanol. Among fluorescent probes that detect Reactive Oxigen Species(ROS), Liperfluo is the only compound that can specifically detect lipid peroxides. Since the excitation and emission wavelengths of the oxidized Liperfluo are 524 nm and 535 nm, respectively, both a photo-damage against a sample and an auto-fluorescence from the sample can be minimized. The tetraethyleneglycol group linked to one end of diisoquinoline ring helps its solubility and dispersibility to aqueous buffer. Though Liperfluo oxidized form is almost nonfluorescent in an aqueous media, it emits fluorescence in lipophilic sites such as in cell membranes. Therefore it can easily be applied
to lipid peroxide imaging by a fluorescence microscopy and a flow cytometric analysis for living cells.

Procedure
1. Innocurate SH-SY5Y cells(6.0 x 105 cells/well) to a 6-well plate.
2. Incubate the plate at 37 ºC for overnight.
3. Add Liperfluo, DMSO solution(final conc. 20 μM) and incubate at
37 ºC for 15 min.
4. Add either Cumene Hydroperoxide(final conc. 100 μM) or AIPH*(final conc. 6 mM).
5. Incubate at 37 ºC for 2 hours.
6. Observe fluorescent by microscope**.
