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 TRITC provides red-orange fluorescence of unparalleled brightness and photostability. Demonstrating very little nonspecific staining, Rhodamine phalloidin allows high-contrast discrimination of actin staining. Rhodamine phalloidin is one of the most commonly used fluorescent phalloidin conjugates in the literature, as evidenced by over 1,500 citations (maintained in our in-house database).

Use in Multiple Applications
Rhodamine phalloidin can be used to visualize and quantitate F-actin in tissue sections, cell cultures, or cell-free preparations. Rhodamine phalloidin staining is fully compatible with other fluorescent stains used in cellular analyses including fluorescent proteins, Qdot™ nanocrystals, and Alexa Fluor™ conjugates including secondary antibodies. For research use only.
