Application【应用】
Atto 565 is a new label with high molecular absorption (120.000) and quantum yield (0.9) as well as sufficient stoke's shift (excitation maximum 563 nm, emission maximum 592 nm). Due to an insignificant triplet formation rate it is well suited for single molecule detection applications. Maleimides are well suited for coupling to thiol groups. This is similar to iodacetamides, but maleimides do react more thiol selective. They do not show significant reaction with histidine or methionine. Hydrolysis of maleimides to a mixture of isomeric nonreactive maleamic acids can compete significantly with thiol modification, particularly above pH 8. Maleimides may be used for labeling of amines, which usually requires a higher pH than reaction of maleimides with thiols.
