Phalloidin is a phallotoxin produced by death cap mushroom Amanita phalloides. It is a cyclic peptide, which interacts with actin, and this was first identified in phalloidin-poisoned rats. It is a heptapeptide, cyclic in nature, with a crosslink between tryptophan at position 6 and cysteine at position 3. The side chain of amino acid 7 (γ-δ-dihydroxyleucine) in phalloidin, is accessible to modifications, through which florescent labelled phalloidin compounds can be produced.
Application:
Fluorescent phallotoxin which may be used to identify filamentous actin.
Phalloidin-Tetramethylrhodamine B isothiocyanate has been used:-
In Immunofluorescence for staining Filamentous actin (F-actin)
To stain cells during immunocytochemical and cytochemical analysis
To label actin microfilaments for fluorescence microscopy
