Azide-containing FLAG Reagents

Azide-containing FLAG tag reagents can be used for the introduction of a FLAG-tag to terminal Alkyne and strained Alkyne (e.g. DBCO)-labeled biomolecules via Cu(I)-catalyzed Alknye-Azide (CUAAC) or Cu(I)-free strain-promoted Alkyne-Azide Click Chemistry (SPAAC) reaction, respectively.

Molecule solubility and efficient FLAG-tag detection is ensured by the integrated PEG-linker.
