In Vitro Phalloidin staining will not work with methanol-fixed cells, probably because of the disruption of actin filament integrity, but it will work with cells fixed in 0.2% glutaraldehyde in PBS. For fluorescein isothiocyanate (FITC)-Phalloidin (or rhodamine isothiocyanate [RITC]-Phalloidin), the excitation wavelength maximum will be near 495 nm (or 550 nm) and the emission wavelength maximum will be ~520 nm based on H2O at pH 8.0 as the solvent (575 nm with methanol as the solvent). The emission spectrum of fluorescein can depend on the environmental pH and/or ionic strength[1].
Cell Assay Prepare a 1:200 dilution of the stock solution (300 units/mL) of fluorescein Phalloidin or rhodamine Phalloidin using PBS. Aspirate the cell medium from the cells grown on glass coverslips and rinse the cells three times with PBS. Fix the cells for 10 min in the 3.7% formaldehyde solution. Rinse the fixed cells three times for 5 min each in PBS. Permeabilize the cells for 5 min in the 0.2% Triton X-100 solution. Rinse the fixed cells three times with PBS. Label the cells with the fluorescein or rhodamine Phalloidin for 5 to 10 min at room temperature. Rinse the cells three times in PBS for 5 min each time. Mount the cell and view the cells using either the fluorescein or rhodamine filter set, depending on the probe[1].
