| Hazard Information | Back Directory | [Description]
Thiol mono-reactive Cyanine3 dye. This reagent can be used to attach Cyanine3 fluorophore (an analog of Cy3?) to proteins and peptides containing cysteine residues, as well as to other thiolated molecules (such as thiol-containing oligonucleotides)._x000D_
_x000D_
Cystines should be reduced with TCEP (tris-carboxyethylphosphine) or other appropriate reductant prior to the labeling._x000D_
_x000D_
Labeling with Cyanine3 maleimide is selective, and efficient._x000D_
_x000D_
We recommend using water-soluble Sulfo-Cyanine3 maleimide for the labeling of antibodies and other sensitive proteins. | [Chemical Properties]
