General description
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.
