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 Alexa Fluor 594 provides red fluorescence of unparalleled brightness and photostability. Demonstrating very little nonspecific staining, Alexa Fluor 594 phalloidin allows high-contrast discrimination of actin staining.

Use in Multiple Applications
Alexa Fluor 594 phalloidin can be used to visualize and quantitate F-actin in tissue sections, cell cultures, or cell-free preparations. Alexa Fluor 594 phalloidin 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.

Frequently asked questions (FAQs)

Can I combine Click-iT or Click-iT Plus reactions with phalloidin conjugates used for actin staining?

We do not recommend using phalloidin conjugates for staining actin in combination with traditional Click-iT or Click-iT Plus reactions since phalloidin is extremely sensitive to the presence of copper.

For staining actin in combination with traditional Click-iT or Click-iT Plus reactions, we recommend using anti-α-actin antibodies for staining actin in the cytoskeleton. You can find a list of our actin antibodies here.

Another option would be to use the Click-iT Plus Alexa Fluor Picolyl Azide Toolkit (Cat. Nos. C10641, C10642, C10643). These Click-iT Plus toolkits provide Copper and Copper protectant separately which makes it easier to titrate the copper concentration to obtain optimal labeling with minimal copper-mediated damage. You may need to optimize the click reaction with the lowest possible concentration of copper and then perform the phalloidin staining.

I'm trying to label my paraffin sections for F-actin with a phalloidin conjugate, but I'm not seeing any signal. Why?

When cells and tissues are treated with solvents such as xylene or acetone (for example during deparaffinization of tissue sections), it affects the F-actin in a way that prevents phalloidins from binding. Phalloidin may be used with cryosections, which are not typically washed with organic solvents, or anti-actin antibodies may be used.
