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.

Furyl-Alanine: A Novel Photo-Click Amino Acid
2-Furyl-alanine can be incorporated into peptides via SPPS or by using enzymatic approaches. UV-irradiation in the presence of oxygen and a photosensitizer converts furyl-alanine to an intermediate that selectively reacts with certain nucleophiles. This property can be employed for site-specific labeling of peptides and proteins.

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).

Fmoc-Phe-Aca: Fluorescent Internalization Reporter for Cell Penetrating Peptides (CPPs)
The Fmoc-L-Phe-Aca pseudo-dipeptide is a useful reporter group for the successful internalization of CPPs. Phe quenches the fluorescence of Aca. Internalization of the peptide containing Phe-Aca leads to proteolytic cleavage of the Phe-Aca bond and thus to fluorescence.
