Alexa Fluor™ 555 Phalloidin is a bright, photostable red-orange fluorescent Alexa Fluor™ 555 dye Binding high-affinity F-actin probe.

•Selective staining of F-actin
• Excellent fluorescence properties
•Excitation/emission wavelength: 555/565 nm
• Better than antibody staining
• Suitable for fixed and permeabilized samples

Provides excellent actin staining results
Phalloidin is a bicyclic peptide isolated from the lethal Amanita "death cap" mushroom A class of toxins commonly used to selectively label F-actin in imaging applications. The binding properties of fluorescently labeled phalloidin to actin from different species, including plants and animals, are almost identical. Phalloidin binds to F-actin with high selectivity, while Alexa Fluor™ 555 provides red-orange fluorescence with excellent brightness and photostability. Alexa Fluor™ 555 Phalloidin rarely causes non-specific staining and allows high contrast differentiation of actin staining.

Can be used in a variety of applications
Alexa Fluor™ 555 Phalloidin can be used to target F-actin in tissue sections, cell cultures, or cell-free preparations Perform visualization and quantification. Alexa Fluor™ 555 Phalloidin Stain is fully compatible with other fluorescent stains used in cell analysis procedures, including fluorescent proteins, Qdot™ Nanocrystals, and other Alexa Fluor™ conjugates (including secondary antibodies).
