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.
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.
