CF543 phalloidin conjugate is the mushroom toxin phalloidin labeled with our superior orange fluorescent dye CF543. Because of their highly specific binding to F-actin, fluorescent phalloidin conjugates are excellent tools for cytoskeleton studies. CF543 has an excitation/emission at 541/560 nm, respectively. Bioconjugates of the dye are brighter than those of Alexa Fluor? 543.
