CF™568 maleimide is a superior red fluorescent dye with a maleimide reactive group, which can be used to label a target molecule with a thiol group. CF™568 has an excitation spectrum optimally matching the 568 nm line of the Ar-Kr mixed-gas laser. Protein conjugates of the dye are much brighter than those of Alexa Fluor® 568. In addition, the photostability of CF™568 is superior to that of Alexa Fluor® 568, making CF™568 a much better choice for demanding applications, such as confocal microscopy and single molecule imaging.
