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.

Actin filaments staining in HeLa cells. Actin filaments (green) were stained with CytoPainter Phalloidin-iFluor 488 reagent (ab176753); tubulin filaments were stained with a mouse anti-tubulin antibody/goat anti-mouse IgG (red). Nuclei were stained with Hoechst 33342.
