Protected Cyanine5 hydrazide, a dye with a reactivity for carbonyl groups (aldehydes and ketones) activated by acid.

Cyanine7.5 maleimide is a thiol reactive near-infrared dye for labeling of protein SH groups.

Tetrazine derivative of the fluorophore Cyanine3. Tetrazines react extremely quickly with strained alkenes (such as trans-cyclooctenes, cyclopropenes), and some strained alkynes.

Cyanine5.5 alkyne is a NIR (near infrared) dye azide for copper-catalyzed сlick сhemistry.

Amino derivative of Cyanine5.5, a far red emitting fluorescent cyanine dye.

Far red / near infrared fluorescent Cyanine5.5 dye derivative for click chemistry.

Cyanine5.5 dye, free acid form, unactivated. The dye can be considered non-reactive for most applications.

Cyanine5.5 is a far-red / NIR emitting dye that is useful for bioimaging studies. Cyanine5.5 DBCO is a derivative of the dye with a cycloalkyne moiety for copper-free click chemistry.

Non-functionalized Сyanine5.5 dye derivative with good solubility in organic solvents and bright fluorescence in the far-red spectrum range.

Cyanine5.5 hydrazide is a carbonyl reactive NIR dye which is particularly suitable for the labeling of periodate oxidized glycoproteins, i.e. antibodies.
