Phalloidin-iFluor 488 Reagent

Phalloidin-iFluor 488 Reagent ab176753 is one of a series of phalloidin conjugates that bind to actin filaments, also known as F-actin. The iFluor 488 dye can be easily detected with a fluorescent microscope at Ex/Em = 493/517 nm.

Our phalloidin conjugates are convenient probes for labeling, identifying and quantifying animal or plant actin filaments in formaldehyde-fixed and permeabilized tissue sections, cell cultures or cell-free experiments. They can also be used with paraffin-embedded samples that have been de-paraffinized.

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.
