CF350 phalloidin conjugate is the mushroom toxin phalloidin labeled with our superior blue fluorescent dye CF350. Because of their highly specific binding to F-actin, fluorescent phalloidin conjugates are excellent tools for cytoskeleton studies. CF350 is spectrally similar to the traditional blue fluorescent dye, AMCA. However, compared to AMCA, CF350 is more water-soluble, more photostable and at least 50% more fluorescent on proteins. CF350 is at least as bright as Alexa Fluor? 350 and thus can be a direct replacement for the latter for all applications.
