Diazo Biotin-Azide is suitable for the introduction of a biotin moiety to terminal Alkyne- and strained Alkyne (e.g. DBCO)-labeled biomolecules via Cu(I)-catalyzed Alkyne-Azide (CUAAC) or Cu(I)-free strain-promoted Alkyne-Azide Click Chemistry (SPAAC) reaction, respectively.
The biotinylated molecule can be selectively captured through conventional affinity biotin - streptavidin purification and released under mild buffer conditions with a 50 mM sodium dithionite (Na2S2O4) solution 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.
General Procedure for Release
Incubate beads in phosphate buffer solution (pH 7.4) containing 50 mM Na2S2O4 (2 x 60 minutes) at room temperature. References - might be used as starting point for the set up of your individual assay.
