Alkyne derivative of AF 488 dye for copper-catalyzed cycloaddition to azides (CuAAC). AF 488 alkyne is used for fluorescent labeling of azidated biomolecules, polymers, and surfaces. AF 488 is sulfonated rhodamine, a bright, photostable, and hydrophilic fluorophore that emits in the green channel (absorption max. is at 495 nm, emission max. is at 519 nm).

TBTA ligand

TBTA is one of the most widely used water-insoluble ligands for copper-catalyzed azide-alkyne cycloadditions (CuAAC).

AF 532 carboxylic acid

Non-reactive form of AF 532 fluorescent dye with a free carboxyl group.

AmdU (5-Azidomethyl-2'-deoxyuridine)

Azidomethyldeoxyuridine (AmdU) is an azide-contained nucleoside that is incorporated into nascent DNA by cellular polymerases. The azide groups attached to DNA this way can be subsequently modified with alkynes or cycloalkynes via copper-catalyzed or strain-promoted click reaction.
