Phalloidin-Fluorescein Conjugate

Phalloidin-fluorescein conjugate is a fluorescent dye used to label actin filaments (F-actin). Phalloidin binds to F-actin and prevents depolymerization.1 It also inhibits the ATP hydrolysis action of F-actin.2 Phalloidin-fluorescein can be used to label tissue, cells, and cell-free preparations that have been formaldehyde-fixed and permeabilized. It displays excitation/emission maxima of 498/517 nm, respectively. Phalloidin-fluorescein can be used at nanomolar concentrations in conjunction with additional dyes for multi-labeling purposes.WARNING This product is not for human or veterinary use.
