Sulfo-SBED Biotin Label Transfer Reagent and Kit -

Co-immunoprecipitations, pull-down assays, far-Western analysis and label transfer reactions are excellent and widely used in vitro approaches to discover or confirm protein interactions. These methods verify that an interaction may exist in vivo between the binding partners identified. The artificial protease-based method embodied in the new ProFound Protein Interaction Mapping Kit enables the investigator to inquire more deeply into a known binding pair to gain additional information regarding the interaction site.
