Thermo Fisher Scientific

Product Name:

Alexa Fluor® 488 Phalloidin

Catalog Number:

A12379

Alexafluor 488 Phalloidin was used to stain actin in order to quantify actin structures such stress fibers, filopodia and lamellipodia in fixed cells. By treating cells with various compounds or by reducing levels of specific proteins by siRNA treatments, the affects on the actin cytoskeleton can be visualized using this product. As phalloidin is a chemical stain, that is highly specific to actin, it is superior to antibody staining and far simpler to use.

Experimental Design and Results Summary

Application

F-actin staining of fixed mammalian cells

Starting Material

Fixed mammalian cells. Examples: Human U2OS cells, HUVECs, Hacats and HeLa. Mouse NIH3T3's and primary fibroblasts

Protocol Overview

This product is used at a 1:200 dilution (in PBS). 30 minutes of incubation is sufficient for complete F-actin staining.

Tips

Can be used in combination with immunfluorecent staining procedures.
