Get Superior Results in Actin Staining Studies
Phalloidin is a bicyclic peptide belonging to a family of toxins isolated from the deadly Amanita phalloides “death cap” mushroom and is commonly used in imaging applications to selectively label F-actin. Fluorescently-labeled phalloidin has virtually identical binding properties with actin from different species including plants and animals. Phalloidin binds F-actin with high selectivity while Alexa Fluor 647 provides far-red fluorescence of unparalleled brightness and photostability. Demonstrating very little nonspecific staining, Alexa Fluor 647 phalloidin allows high-contrast discrimination of actin staining.


  • Selectively stains F-actin
  • Outstanding fluorescence performance
  • Excitation/Emission: 650/668nm
  • Superior to antibody staining
  • Optimal for fixed and permeabilized samples
  • Fully compatible with other fluorescent stains used in cellular analyses including fluorescent proteins, Qdot™ nanocrystals, and other Alexa Fluor conjugates including secondary antibodies


Cell Analysis, Cell Structure, Cytoskeleton. Used to visualize and quantitate F-actin in tissue sections, cell cultures, or cell-free preparations.
