Cyanine5 is a universal red emitting dye with a very high extinction coefficient, and good quantum yield. This tetrazine derivative reacts very quickly with trans-cyclooctenes and cyclopropenes with the formation of stable conjugates.

Cyanine5 carboxylic acid, unactivated dye. An analog of Cy5®; free carboxylic acid.

Phosphoramidite derivative of Cyanine5 for use in oligonucleotide synthesis.

Cyanine7.5 tetrazine is a tetrazine derivative for TCO ligation and Diels-Alder reaction containing a NIR fluorophore and suitable for in vivo infrared imaging.

Near infrared fluorophore functionalized with hydrazide moiety. Reactive against carbonyl compounds, useful for the labeling of saccharides, and antibodies after periodate oxidation.

Long-wavelength NIR fluorescent dye azide for click chemistry.

Cyanine7 alkyne is a near infrared (NIR) dye alkyne for click chemistry.

Reactive near infrared (NIR) dye for click chemistry containing a terminal alkyne group.
