    AFDye™ 568 Maleimide (Alexa Fluor® 568 C5 Maleimide equivalent) is a bright, and photostable, red-fluorescent probe optimally excited by the 568 nm laser line on the Ar-Kr mixed-gas laser. AFDye™ 568 Maleimide is water-soluble and its fluorescence is pH independent over a wide pH range. The brightness and photostability of this dye are best suited to direct imaging of low-abundance targets.

    AFDye™ 568 Maleimdie (Alexa Fluor 568 C5 Maleimdie equivalent) is an sulfhydryl-reactive, red fluorescent dye routinely used to label proteins or antibodies through the thiol (Cys), thiol-modified oligonucleotides, and other thiol-containing biomolecules. AFDye™ 568 dye can be used for proteins labeling at high molar ratios without significant self-quenching, enabling brighter conjugates and more sensitive detection.

    AFDye™ 568 is a water-soluble, photostable, and bright orange dye with pH insensitive emission from pH 4 to pH 10. The excitation of AFDye™ 568 dye ideally suited for the 568 nm laser line on the Ar-Kr mixed-gas laser. AF™ 568 dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates often used for generation of stable signal in imaging and flow cytometry.
