Ready-to-use kit eliminates the need to prepare the necessary buffers or purchase the critical reagents necessary to perform a label transfer experiment. Key reagents, Sulfo-SBED and DTT, are supplied in unique, no-weigh, single-use packaging.


  • Sulfo-NHS ester reacts with primary amines at pH 7-9
  • Aryl azide conjugates randomly when activated with UV light
  • Cleavable disulfide bond allows biotin label transfer
  • Discover protein interactions without radiolabeling
