BODIPY 581/591 C11

C11 BODIPY 581/591 is a lipid-soluble ratiometric fluorescent indicator of lipid oxidation. Upon oxidation, its excitation maximum shifts from 581 to 500 nm and the emission maximum shifts from 591 to 510 nm. C11 BODIPY 581/591 has been used in the quantitation of ferroptosis.

BODIPY 581/591 C11 is an oxidation-sensitive fluorescent fatty acid analog with fluorescent properties in the red range of the visible spectrum (emission maximum 595 nm), allowing its application in fluorescence microscopy. BODIPY 581/591 C11 is easily incorporated into membranes and fluoresces red in the intact state but shifts to green upon free radical-induced oxidation. This characteristic is highly advantageous; it makes the ratio-imaging of oxidant activities at the (sub)cellular level feasible. In addition, the fluorescent properties of C11-BODIPY581/591 allow the use of this probe in fast- and medium-throughput screening of antioxidants in living cells and model membranes in a multiwell/fluorescence reader approach.

BODIPY 581/591 C11 is a BODIPY borofluoroprene derivative with good light stability and low fluorescence artifacts. BODIPY 581/591 C11 can be used for study lipid peroxidation and antioxidant properties in living cells, or detect ferroptosis by reaction with hydroxyl radicals. BODIPY 581/591 C11 is emitted at 591 nm (reduced prototype), or redshifted to 510 nm (oxidized type). The excitation wavelengths were 581 nm (reduced prototype) and 500 nm (oxidized type)[1].
