Rhodamine Phalloidin Reagent ab235138 is one of a series of phalloidin conjugates that are used to stain actin filaments in fluoresence microscopy. The tetramethyl rhodamine dye can be easily detected with a fluorescent microscope at Ex/Em = 546/575 nm.
Phalloidin conjugates are convenient probes for labeling, identifying and quantitating animal or plant actin filaments in formaldehyde-fixed and permeabilized tissue sections, cell cultures or cell-free experiments.

Staining fixed cell or tissue samples with phalloidin conjugates is very simple; it requires a single 20-90 min incubation with the phalloidin, followed by 3 short wash steps. Phalloidin staining can be combined with antibody-based staining by adding the phalloidin conjugate during either the primary or secondary antibody incubation step.
When used in unfixed samples, phalloidin binding leads to a decrease in the disassociation rate of actin subunits from the ends of actin filaments, essentially stabilizing actin filaments through the prevention of filament depolymerisation.
