Alexa Fluor® 546 phalloidin is a high-affinity F-actin probe conjugated to our bright, photostable, orange-fluorescent Alexa Fluor® 546 dye.
• Selectively stains F-actin • Outstanding fluorescence performance • Excitation/Emission: 556/570 nm • Superior to antibody staining • Optimal for fixed and permeabilized samples
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® 546 provides orange fluorescence of unparalleled brightness and photostability. Demonstrating very little nonspecific staining, Alexa Fluor® 546 phalloidin allows high-contrast discrimination of actin staining.
Use in Multiple Applications Alexa Fluor® 546 phalloidin can be used to visualize and quantitate F-actin in tissue sections, cell cultures, or cell-free preparations. Alexa Fluor® 546 phalloidin staining is fully compatible with other fluorescent stains used in cellular analyses including fluorescent proteins, Qdot® nanocrystals, and other Alexa Fluor® conjugates including secondary antibodies.
