Atto 488 Maleimide is a hydrophilic fluorescent label with high molecular absorption (90.000) and quantum yield (0.80). The fluorescence activity is excited at a maximum of 501nm, and the maximum emission is 523nm. Atto 488 Maleimide is optimized for argon laser excitation and characterized by high photostability. Hydrolysis of maleimides to a mixture of isomeric nonreactive maleamic acids can compete significantly with thiol modification, particularly above pH 8. Post coupling to a substrate, the label carries a net electrical charge of -1.
Application
Atto 488 Maleimide is used for labelling amines, which usually requires a higher pH than the reaction of maleimides with thiols. It is a well-suited fluorescent label for thiol groups.

Dynamic reorganization of the actomyosin cytoskeleton allows fast modulation of the cell surface, which is vital for many cellular functions. Myosin-II motors generate the forces required for this remodeling by imparting contractility to actin networks. However, myosin-II activity might also
Curved membranes are an essential feature of dynamic cellular structures, including endocytic pits, filopodia protrusions and most organelles. It has been proposed that specialized proteins induce curvature by binding to membranes through two primary mechanisms: membrane scaffolding by curved proteins

In C. elegans, the BH3-only domain protein EGL-1, the Apaf-1 homolog CED-4 and the CED-3 caspase are required for apoptosis induction, whereas the Bcl-2 homolog CED-9 prevents apoptosis. Mammalian B-cell lymphoma 2 (Bcl-2) inhibits apoptosis by preventing the release of
Investigations into the fate of small interfering RNA (siRNA) after transfection may unravel new ways to improve RNA interference (RNAi) efficiency. Because intracellular degradation of RNA may prevent reliable observation of fluorescence-labeled siRNA, new tools for fluorescence microscopy are warranted
