FlAsH-EDT2 is an organoarsenic compound with molecular formula C24H18As2O5S4. Its structure is based around a fluorescein core with two 1,3,2-dithiarsolane substituents. It is used in bioanalytical research as a fluorescent label for visualising proteins in living cells. FlAsH-EDT2 is an abbreviation for … See more FlAsH-EDT2 can be prepared in three steps from fluorescein (see figure). See more Many studies show that trivalent arsenic compounds bind to pairs of cysteine residues. This binding is responsible for the toxicity of many arsenic compounds. Binding is reversed … See more FlAsH-EDT2 enables less toxic and more specific fluorescent labeling that is membrane permeable. The modification of the fluorescein moiety also allows multicolor analysis. … See more FlAsH becomes fluorescent upon the binding of tetracysteine motif. It is excited at 508 nm and emits 528 nm, a green-yellow, of free fluorescein. The quantum yield is 0.49 for 250 nM FlAsH is bound to a model tetracysteine-containing peptide in a phosphate … See more WebJan 23, 2024 · Constructs were lentivirally transduced for subsequent CD36 labeling with fluorescein-arsenical hairpin-binder (FlAsH).
