sulfo-Cyanine5.5 NHS ester is an amine-reactive activated ester of sulfonated far-red Cyanine5.5 fluorophore, an analog of Cy5.5®. This is a reagent of choice for the labeling of antibodies, sensitive proteins, and others which require reactions in a purely aqueous environment or without any significant additions of organic co-solvents.
The dye is well-suitable for non-invasive in vivo NIR imaging and applications requiring low fluorescent background.

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.BDP 630/650 azide
BDP 630/650 is a bright borondipyrromethene-based fluorophore for the far red area of the spectrum. It possesses a high extinction coefficient and quantum yield. This is an azide for сlick chemistry labeling.Cyanine5.5 azide
