CY7-SE Triethylamine is a fluorescence labeling agent (Ex=700-770 nm，Em=790 nm) used for labeling proteins, peptides, antibodies, and oligonucleotides.

Sulfo-Cyanine5 is an analog of Cy8, a very popular fluorophore, therefore this reagent is compatible to a wide range of standard fluorescent instrumentation such as imagers, plate readers, and microscopes.

CY5-SE (Sulfo-Cyanine5 Succinimidyl Ester) is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides (Excitation: 649 nm, Emission: 670 nm).

CY5-SE triethylamine salt (Fluorolink Cy5 triethanolamine salt) is a hydrophilic amine-reactive fluorescent probe. It displays excitation/emission maxima of 646/662 nm, respectively. Cy5-SE-conjugated ligands have been used in the characterization of hematopoietic tumor microenvironments.
