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.
