Phalloidin–Atto 430LS

NA.32

Atto 430LS is a new fluorescent label featuring an extraordinary large Stokes-Shift of 114 nm. Thus its emission spectrum is almost completely separated from its absorption spectrum, making the dye highly suitable for multiplexing experiments. Atto 430LS is very hydrophilic and shows excellent water solubility. The dye exhibits a high fluorescence quantum yield, which is only slightly reduced after conjugation to biomolecules, e.g. proteins, even at high degrees of labeling (DOL).
Atto 430LS is an anionic dye. After conjugation to a substrate the dye carries a net electrical charge of ^-1. The fluorescence is excited most efficiently in the range 400 - 460 nm.
Phalloidin, a bicyclic heptapeptide, is a very strong binding reagent to actin. Fluorescent labeled phalloidin has become a useful tool to investigate the distribution of F-actin within the cytoskeleton of cells by fluorescence microscopy.
