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 ApplicationsAlexa 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.
