Alexa Fluor™ 546 Phalloidin (Invitrogen™)

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.
