  2. THPTA: Ligand-accelerated Click Chemistry in Aqueous Solution

    Polytriazole ligands such as THPTA accelerate the copper-catalyzed azide-alkyne cycloaddition (CuAAC), or “Click”, reaction. Moreover, with the use of further additives, polytriazoles facilitate CuAAC even in live cells by significantly lowering the bioavailability of the copper catalyst.

  3. Targeted and Reversible Biotinylation with Biotin-SS-Tyramide

    Our new Biotin-SS-Tyramide linker is a valuable tool for peroxidase-promoted targeted protein biotinylation. By using peroxidase-tagged antibodies, proteins and protein clusters can be selectively biotinylated, and then isolated using streptavidin. The biotin tag can be subsequently removed using reducing agents (e.g. glutathione).

  5. Biotin Tyramide Reagents for Tyrosine-/Protein-Biotinylation

    Tyramine compounds are converted to highly reactive radicals by horseradish peroxidase in presence of H2O2 which preferentially react with surface exposed tyrosines. Biotin Tyramide and Biotin-PEG-Tyramide therefore are ideal reagents used for tyrosine-/protein-biotinylation.
