  • 产品概述

    Phalloidin-iFluor 488 Reagent | CytoPainter (ab176753) is one of a series of phalloidin conjugates that selectively binds 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 actin filaments in formaldehyde-fixed and permeabilized tissue sections, cell cultures or cell-free experiments. They can also be used in paraffin-embedded samples that have been de-paraffinized.

    Phalloidin binds to actin filaments much more tightly than to actin monomers, leading to a decrease in the dissociation rate of actin subunits from filaments ends, essentially stabilizing actin filaments through the prevention of filament depolymerization.

  • 说明

    Actin is a globular, roughly 42-kDa protein found in almost all eukaryotic cells. It is also one of the most highly conserved proteins, differing by no more than 20% in species as diverse as algae and humans. Actin is the monomeric subunit of two types of filaments in cells: microfilaments, one of the three major components of the cytoskeleton, and thin filaments, part of the contractile apparatus in muscle cells. Thus, actin participates in many important cellular processes including muscle contraction, cell motility, cell division and cytokinesis, vesicle and organelle movement, cell signaling, as well as the establishment and maintenance of cell junctions and cell shape.

Whole mount IF for the inner ear

Excellent Excellent 5/5 (Ease of Use)
I used abcam's phalloidin-488 for whole mount IF of mouse inner ear (sensory epithelia). It stains actin so stereocilia are stained very strong. Diluted 1:1000 in PBS and incubated for 2 hours in RT.

CytoPainter Phalloidin-iFluor 488

Excellent Excellent 5/5 (Ease of Use)
For our experiments, the macrophage J774A.1 cell line was placed in 24-well tissue culture plates containing round glass coverslips. After 24h, cells were washed four times and fixed with cold paraformaldehyde (3.2% in PBS) for 20 min at room temperature. After being fixed, the cells were permeabilized with Triton X-100 (0.1% in PBS) for 5 min at room temperature and washed four times with PBS. CytoPainter Phalloidin-iFluor 488 (1:1000 dilution in 1%BSA-PBS), which binds polymerized F-actin, was used to identify actin filaments and fibers. Coverslips were mounted on glass slides with mounting medium containing DAPI.
Preparations were examined with a Nikon A1R confocal scanning laser microscope equipped with 405nm/450nm (DAPI) and 488nm/525nm (CytoPainter iFluor) lasers. Images were captured at random with a ×20 (A), ×40 (B) or ×60 (C, D) objectives, and processed using the NIS-Elements 3.2 software. Scale bars: A, 50µm B, 10 µm.

I stained the murine osteocyte cells (MLO-Y4 cells line) with Phalloidin-iFluor 488, DAPI staining and sclerostin antibody labbeled with iFluor 550. I used this protocol :
Fixed cells with PFA 4% for 20 min at room temperature
Wash 3 times for 5 min with PBS
Incubate for 10 min at room temperature with PBS-Triton 0.1%
Wash 3 times for 5 min with PBS-Tween 0,1%
Blocked for 30 min at room temprature with PBS-BSA 1%
Incubate with primary antibody in PBS-BSA 1% overnight at 4°C (antibody against sclerostin in this case)
Wash 3 times for 5 min with PBS-Tween 0,1%
Incubate with secondary antibody in PBS-BSA1% for 1h at room temperature in the dark (antibody anti-goat in this case)
Wash 3 times for 5 min with PBS-Tween 0,1%
Incubate with Phalloidin 488 PBS-BSA 1% 60 min at room temperature in the dark
Wash 3 times for 5 min with PBS-Tween 0,1%
Staining with DAPI for 15 min at room temprature in the dark
Wash 3 times for 5 min with PBS-Tween 0,1%
