CyDye Mono-Reactive Maleimides are particularly suited to antibody labeling since the dye molecules are introduced away from the antibody binding site, increasing the chance that functionality of the labeled molecule will be unimpaired.

• Selective labeling of free sulfhydryl groups such as cysteine residues in peptides, proteins, and oligonucleotides
• Particularly effective for labeling antibodies
• Large range of bulk packs available for maximum convenience and economy
• Example protocols included with each dye pack
