XFD488 is manufactured by AAT Bioquest, and it has the same chemical structure of Alexa Fluor® 488 (Alexa Fluor® is the trademark of ThermoFisher). XFD488 phalloidin conjugate is chemically equivalent to Alexa Fluor® 488 phalloidin. This green fluorescent phalloidin conjugate selectively binds to F-actins. Used at nanomolar concentrations, phalloidin derivatives are convenient probes for labeling, identifying and quantitating F-actins in formaldehyde-fixed and permeabilized tissue sections, cell cultures or cell-free experiments. Fluorescent phalloidin derivatives have been used as an important tool in the study of actin networks at high resolution. AAT Bioquest offers a variety of fluorescent phalloidin derivatives with different colors for multicolor imaging applications.

Protocol Summary
- Prepare samples in microplate wells
- Remove liquid from samples in the plate
- Add XFD488 Phalloidin Conjugate solution (100 μL/well)
- Stain the cells at room temperature for 20 to 90 minutes
- Wash the cells
- Examine the specimen under microscope with FITC filter
Storage and Handling Conditions
The solution should be stable for at least 6 months if store at -20 °C. Protect the fluorescent conjugates from light, and avoid freeze/thaw cycles. Note: Phalloidin is toxic, although the amount of toxin present in a vial could be lethal only to a mosquito (LD50 of phalloidin = 2 mg/kg), it should be handled with care.PREPARATION OF WORKING SOLUTION
XFD488 Phalloidin Conjugate working solution
Add 1 µL of XFD488 Phalloidin Conjugate solution to 1 mL of PBS with 1% BSA. Note: The stock solution of phalloidin conjugate should be aliquoted and stored at -20 °C. protected from light. Note: Different cell types might be stained differently. The concentration of phalloidin conjugate working solution should be prepared accordingly.SAMPLE EXPERIMENTAL PROTOCOL
Stain the cells
- Perform formaldehyde fixation. Incubate cells with 3.0–4.0 % formaldehyde in PBS at room temperature for 10–30 minutes. Note: Avoid any methanol containing fixatives since methanol can disrupt actin during the fixation process. The preferred fixative is methanol-free formaldehyde.
- Rinse the fixed cells 2–3 times in PBS.
- Optional: Add 0.1% Triton X-100 in PBS into fixed cells for 3 to 5 minutes to increase permeability. Rinse the cells 2–3 times in PBS.
- Add 100 μL/well (96-well plate) of XFD488 Phalloidin Conjugate working solution into the fixed cells, and stain the cells at room temperature for 20 to 90 minutes.
- Rinse cells gently with PBS 2 to 3 times to remove excess phalloidin conjugate before plating, sealing and imaging under microscope with FITC filter set.

Figure 1. Fixed and stained HeLa cells.
HeLa cells were fixed with 4% formaldehyde, permeabilized, and blocked. F-actin were stained with XFD488 phalloidin (Cat No. 23153) and nuclei labeled with Nuclear Red™ DCS1 (Cat No. 17552). Images were acquired on a Keyence BZ-X710 all-in-one fluorescence microscope.
