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 Oregon Green 488 provides green fluorescence with brightness superior to fluorescein. Oregon Green 488 is a fluorinated analog of fluorescein with greater photostability and a lower pKa, making its fluorescence essentially pH insensitive in the physiological pH range. Demonstrating very little nonspecific staining, Oregon Green 488 phalloidin allows high-contrast discrimination of actin staining.

Use in Multiple Applications
Oregon Green 448 phalloidin can be used to visualize and quantitate F-actin in tissue sections, cell cultures, or cell-free preparations. Oregon Green 448 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.
