Product Description
DPPP is a non-fluorescent triphenylphosphine compound. It reacts with hydroperoxide to generate DPPP oxide that emits fluorescence at 352 nm excitation and 380 nm emission wavelengths (Fig. 1). Post-column HPLC method is used to determine phospholipid peroxide in sample solutions.
