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.

In eukaryotic cells, Hsp90 chaperones assist late folding steps of many regulatory protein clients by a complex ATPase cycle. Binding of clients to Hsp90 requires prior interaction with Hsp70 and a transfer reaction that is mediated by the co-chaperone Sti1/Hop.

Inter- or intramolecular distances of biomolecules can be studied by Förster resonance energy transfer (FRET). For most FRET methods, the observable range of distances is limited to 1-10 nm, and the labeling efficiency has to be controlled carefully to obtain
