Phalloidin CruzFluor™ 350 Conjugate is a blue fluorescent dye. Phalloidin is a heptapeptide phallotoxin produced by Amanita phalloides, the death cap mushroom. Phalloidin binds and stabilizes filamentous F-actin, preventing the dissociation of paired filaments and disturbing the natural equilibrium between filamentous (polymeric) and globular (monomeric) actin in the cell, as well as inhibit the ATP hydrolysis activity of F-actin. Actin is used by the cell for mechanical processes such as growth, scaffolding of the cytoskeleton, and locomotion, and disruption of this actin equilibrium destroys cellular functioning. The magnitude by which the actin protein differs from species to species is no more than 20%.
These properties of Phalloidin make Phalloidin CruzFluor™ Conjugates a fantastic tool for labeling, identifying and quantitating F-actins. The Phalloidin CruzFluor™ Conjugates are used at nanomolar concentrations with cell-free experiments, cell culture experiments, formaldehyde-fixed, permeabilized tissue sections and the study of actin networks. Because Phalloidin CruzFluor™ Conjugates are offered in different colors the series is excellent for multicolor imaging applications.
