sulfo-Cyanine3 amine

Water soluble cyanine dye with bright fluorescence and high extinction coefficient. Contains an amino group for the conjugation with electrophiles and enzymatic transamination labeling.

AF 343 (Coumarin) X azide

AF 343 (Coumarin) is a blue emitting fluorophore that can serve as a FRET donor for fluorescein (FAM). This azide derivative can be conjugated with alkynes by сlick chemistry. An extended linker arm between the fluorophore and the azide group enhances solubility and provides spatial separation between the dye and the biomolecule.

Cyanine5.5 carboxylic acid

Cy5.5 unactivated free acid cyanine dye.
