Safety Data Sheets

A clickable HaloTag ligand. HaloTag is a modified bacterial haloalkane dehalogenase that reacts with chloralkane-containing ligands to form a covalent HaloTag-ligand conjugate. The reaction between the chloralkane linker and HaloTag is fast and irreversible under physiological conditions and the system has been used extensively to measure protein-protein interactions in cells.

The DBCO moiety shows enhanced kinetics in Click reactions due to its increased strain energy of the cyclooctyne moiety = strain-promoted azide-alkyne cycloaddition. Furthermore, this reaction benefits of increased biocompatibility as there is no requirement for cytotoxic Cu(I) as catalyst.
