Phalloidin-Atto 488

SIGMA/49409 - BioReagent, suitable for fluorescence, ≥90% (HPLC)

Synonym: Atto 488; Atto 488 Phalloidin

Product Type: Chemical

Application:	Phalloidin Atto 488 is used for labeling F-actin in fixed cells since the binding nature is like natural phallacidin. Phalloidin conjugates identify and quantify F-actin in tissues, cell cultures, or cell-free preparations. Since fluorescent Phalloidin Atto 488 conjugates are non-permeable to live cells, it is suitable to identify cells with compromised membranes.
Features and Benefits:	Characteristic features of the Phalloidin Atto 488 are: • Strong Absorption. • High Fluorescence quantum yield. • High Photostability. • Minimal Triplet formation.
General description:	Phalloidin Atto 488is a hydrophilic fluorescent label with high water solubility. Post coupling to a substrate, the fluorescent label carries a net electrical charge of -1. The fluorescence activity is excited efficiently at the 480-515nm range. A suitable excitation source for Phalloidin Atto 488 is the 488 nm line of the Argon-Ion laser.
