BODIPY 581/591 C11 Chemische Eigenschaften,Einsatz,Produktion Methoden
Definition
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.
Advantages
BODIPY 581/591 C11 is a fluorescent radio-probe for indexing lipid peroxidation and antioxidant efficacy in model membrane systems and living cells, with excellent characteristics: (i) emission in the visible range of the electromagnetic spectrum, with good spectral separation of the nonoxidized (595 nm) and oxidized (520 nm) forms; (ii) has a high quantum yield and because of this, low labeling concentrations can be used, ensuring minimal perturbation of the membrane whilst retaining favorable signal to noise ratios; (iii) has a good photo-stability and displays very few fluorescence artifacts; (iv) is virtually insensitive to environmental changes, i.e., pH or solvent polarity; (v) is lipophilic and as such quickly enters membranes; (vi) once oxidized, BODIPY 581/591 C11 remains lipophilic and does not spontaneously leave the lipid bilayer; (vii) BODIPY 581/591 C11 localizes in two distinct pools within the lipid bilayer, a shallow pool at 18 A and a deep pool at < 7.5 A from the center of the bilayer; (viii) is not cytotoxic to rat-1 fibroblasts up to 50 microM; (ix) is sensitive to a variety of oxy-radicals and peroxynitrite, but not to superoxide, nitric oxide, transition metal ions, and hydroperoxides per se; (x) its sensitivity to oxidation is comparable to that of endogenous fatty acyl moieties[1].
