BTTAA is a water-soluble, very effective ligand for Cu(I)-catalyzed Alkyne-Azide click chemistry reactions (CuAAC). It serves a dual purpose: 1) Accelaration of the CuAAC reaction by maintaining the Cu(I) oxidation state of copper sources and 2) Protection of biomolecules from oxidative damage during the labeling reaction[1,2].

BTTAA is a superior alternative to water-insoluble TBTA.

A stock solution can be prepared in ddH2O and subsequently be stored at -20°C. Avoid freeze-thaw cycles.

Presolski et al.[3] and Hong et al.[4] provide a general protocol for CuAAC reactions that may be used as a starting point for the set up and optimization of individual assays.
