Pyrenylbutyric acid is a derivative of pyrene hydrocarbon with a free carboxylic acid function. The reagent is useful as a control for experiments with other reactive pyrene derivatives such as pyrene NHS ester and pyrene azide. Carboxylic acid function can be activated by carbodiimides and other activating reagents.

TAMRA amine, 5-isomer

TAMRA (tetramethylrhodamine) dye, pure 5-isomer, with an amine group for the conjugation with electrophilic reagents (NHS esters, epoxides, etc).

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.
