Phalloidin is a bi-cyclic peptide belonging to a family of toxins isolated from the deadly Amanita phalloides ''death cap'' mushroom and 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 Plus 405 provides violet fluorescence of unparalleled brightness and photostability.
Use in multiple applications
Alexa Fluor Plus 405 Phalloidin can be used to visualize and quantitate F-actin in tissue sections, cell cultures, or cell-free preparations. Its 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.
