Cy3 and Cy5 maleimide mono functional dyes are especially suitable for highly selective peptide, oligonucleotide and protein labeling via thiol maleimide coupling. 

Selectivity and irreversible linkage stabilize crosslinked proteins

  • Highly selective antibody labeling: reduces the probability of the label interfering with subsequent antibody-antigen reactions
  • Irreversible linkage: stabilizes crosslinked proteins
  • Provides an alternative when CyDye NHS esters are unsuitable: such as antibodies where amine labeling might impact antibody-antigen binding affinity
