Invitrogen™ eBioscience™ Phalloidin eFluor™ 570

Phalloidin is a peptide toxin isolated from the Amanita phalloides mushroom. Phalloidin selectively binds F-actin and functions to stablilize actin polymers by inhibiting the dissociation of actin monomers from the filament ends. Because F-actin polymers compose the cytoskeleton of almost all eukaryotic cells, phalloidin conjugates can be useful probes for visualizing the structure of live or fixed cells using microscopy. Phalloidin eFluor™ 570 can be used to label cells of multiple species.

Phalloidin eFluor™ 570 is supplied as a frozen liquid. To prepare the 1000X stock solution, thaw the vial, add 30 μL high-quality anhydrous DMSO, mix and briefly spin down. The resulting solution (phalloidin DMSO stock) should be aliquoted, protected from light and moisture, and stored at -20°C. To prepare a 1X working solution of phalloidin conjugate, add 1 μL of 1000X phalloidin DMSO stock solution to 1 mL of PBS containing 1% BSA.
