Description
Alexa Fluor 488® phalloidin is a high-affinity filamentous actin (F-actin) probe conjugated to our bright, photostable, green-fluorescent Alexa Fluor® 488 dye.• Selectively stains F-actin
• Outstanding fluorescence performance
• Excitation/Emission: 495/518 nm
• Superior to antibody staining
• Optimal for fixed and permeabilized samples
Get Superior Results in Your 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 several advantages over antibodies for actin labeling, including virtually identical binding properties with actin from different species of plants and animals, and low non-specific binding. Phalloidin binds F-actin with high selectivity, while Alexa Fluor® 488 provides green fluorescence of unparalleled brightness and photostability.
Use in Multiple Applications
Alexa Fluor® 488 phalloidin can be used to visualize and quantitate F-actin in tissue sections, cell cultures, or cell-free preparations. Alexa Fluor® 488 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.
