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.

General Procedure for Release

  • Resuspend the washed resin in 1 ml PBS and transfer them to a clear glass vial or quartz cuvette with a tight fitting cap
  • Irridate the suspension with UV light at 345 -375 nm for 1 h under constant agitation (e.g. using a hand held long wave UV lamp such as UVGL-25)
  • Subsequently agitate the sample at 37°C for 1 h. Avoid using a stir bar as this can crush some resins
  • Collect the eluant by centrifugation or gravity flow
  • To increase the recovery rate add PBS to the resin and incubate for an additional 2 -16 h or use a buffer containing 0.1-1% detergent and/or 0,25 -1 M NaCl
