Sulfo-Cyanine5.5 DBCO is a far-red, water-soluble reagent for copper-free click reaction with azides.

Water soluble amine reactive Cyanine5 dye with two NHS ester groups.

Water-soluble far-red fluorescent dye sulfo-Cyanine5.5 in the form of free non-activated carboxylic acid. The dye is useful for calibration and as a non-reactive control.

Cyanine5 hydrazide containing sulfo groups, with good water solubility and carbonyl compounds reactivity.

sulfo-Cyanine5.5 azide is a derivative of water-soluble far-red emitting fluorescent cyanine dye. The azide group can be conjugated by either copper-catalyzed or copper-free click chemistry with alkynes and cycloalkynes.

Thiol reactive maleimide, water soluble cyanine dye for Cy5 channel.

sulfo-Cyanine5 dimethyl is a non-functionalized, water-soluble cyanine dye with bright far-red fluorescence.

sulfo-Cyanine5.5 is a water-soluble far-red emitting dye. This is a thiol-reactive maleimide derivative of sulfo-Cyanine5.5. It is recommended for the labeling of sensitive proteins.

Water-soluble Cyanine5 carboxylic acid, non-activated fluorescent dye.

Water-soluble cycloalkyne for copper-free click chemistry reaction with azides. A derivative of sulfo-Cyanine5.
