Description générale

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.

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
