CF660R phalloidin conjugate is the mushroom toxin phalloidin labeled with our long wavelength fluorescent dye CF660R. The high affinity binding of fluorescent phalloidin conjugates to F-actin make them excellent tools for cytoskeleton studies. CF660R is a bright and exceptionally photostable dye that absorbs at 663 nm and emits fluorescence at 682 nm in the borderline spectral region between far-red and near-IR. CF660R is ideal for confocal microscopy, where it can add a long wavelength color in multi-color imaging.
