生物活性
FlAsH-EDT2 binds to tetracysteine motif (CCXXCC, also called "Cys4"), causes the structure change of FlAsH-EDT2, allowing the absorption of light with specific wavelength and the fluorescence emission[1].
FlAsH-EDT2 also binds to non-specific cysteine-rich intracellular proteins, resulting in background fluorescence as false positive results. FlAsH-EDT2 is suggested to label recombinant proteins with high expression levels[1].
