Phalloidin-FITC
Chemical Name: 7-[(4R)-N5-[[(3',6'-Dihydroxy-3-oxospiro[isobenzofuran-1(3H),9'-[9H]xanthen]-5-yl)amino]thioxomethyl]-4-hydroxy-4-methyl-L-ornithine]phalloidin
Purity: ≥90%
Biological Activity
Key information: Phalloidin-FITC is a green-fluorescent cytoskeleton stain. It binds and labels specifically F-actin.Used for: Phalloidin-FITC can be used to visualize and quantify F-actin in tissue sections, cell cultures or cell-free experiments with optimal results in formaldehyde-fixed and permeabilized cells.
Application: fluorescent microscopy, immunofluorescence (IHC, ICC).
Properties and Photophysical Data: Phalloidin-FITC is composed of the F-actin probe, Phalloidin (Cat. No. 4535), conjugated to Fluorescein isothiocyanate (FITC; Cat. No. 5440) dye. Phalloidin binds F-actin with high selectivity allowing Phalloidin-FITC to stain actin with high-contrast discrimination. Excitation and emission maxima (λ) are 496 nm and 516 nm, respectively.
We suggest making up a stock solution of this product by dissolving the vial contents in 1.5 mL methanol or DMSO. Please refer to the protocol for further information on using this product.
