Phalloidin, Fluorescein Isothiocyanate Labeled

Phalloidin, Fluorescein Isothiocyanate Labeled is a fluorescent phalloidin derivative that can be used to identify filamentous actin. It binds polymeric F actin, stabilizing it and interfering with the function of actin-rich structures, and lowers the critical concentration of actin polymerization. The fluorescein moiety then allows for visualization of F-actin through fluorescence.
