Photocleavable Biotin-Alkyne is suitable for the introduction of a biotin moiety to Azide-labeled biomolecules via Cu(I)-catalyzed Alkyne-Azide Click Chemistry (CUAAC) reaction.
The biotinylated molecule can be selectively captured through conventional affinity biotin - streptavidin purification and released under mild buffer conditions with UV irradiation for subsequent identification by mass spectrometry, ELISA, dot blot or Western blot applications.
Important Product Information
If possible, avoid reducing agents in reaction buffers, this can interfere with the azide stability.
