phalloidin

Phalloidin is a bicyclic heptapeptide found in Amanita mushrooms that binds specifically to F-actin, stabilizing the microfilaments and inhibiting their depolymerization, thereby disrupting cell movement and growth. Phalloidin itself is not fluorescent; it is often conjugated with fluorescent molecules for F-actin staining and is widely used in research such as cytoskeletal imaging and cerebral vascular labeling.

Phalloidin-retramethylrhodamine conjugate is an orange fluorescent probe (ex/em = 546/575 nm) that selectively binds to F-actin. It can be used to localize actin filaments in living or fixed cells, as well as for visualizing individual actin filaments in vitro.

Coumarin-phalloidin is a coumarin-labeled phalloidin. It is an innovative actin probe used for triple immunofluorescence microscopy to observe the cytoskeleton.

Leu-phalloidin is a phallotoxin.

Phalloidin-FITC is a green fluorescent cytoskeleton stain. Binds and labels F-actin. For most fluorescent imaging applications, cells should be fixed and permeablilized. Excitation/emission maxima λ ~496/516 nm.

Phalloidin-Janelia Fluor®646 is a red fluorescent F-actin probe. Phalloidin-Janelia Fluor®646 is composed of the F-actin probe, Phalloidin, conjugated to Janelia Fluor®646. It is suitable for use in confocal and super-resolution microscopy techniques such as dSTORM. Excitation/emission maximum λ = 646/664 nm.
