Despite its toxicity, phalloidin is a valuable tool in scientific research. Fluorescently labeled phalloidin is widely used to stain actin filaments in fixed cells, allowing researchers to study the organization and dynamics of the cytoskeleton. This application is crucial for understanding cellular processes such as cell motility, division, and structural integrity. The specificity of phalloidin for F-actin makes it a powerful agent in microscopy and cell biology studies.
