|Description|| ProFound Label Transfer Sulfo SBED Protein:Protein Interaction Reagent|
A powerful new method known as Label Transfer has rapidly gained traction as an in vitro method for protein interaction discovery. A growing number of publications feature the exclusive Pierce ProFound Sulfo-SBED Biotin Label Transfer Reagent to study a variety of issues relating to protein interactions. • The use of Sulfo-SBED has contributed greatly to published studies on protein:protein interactions. To simplify the method, Pierce has assembled the key components frequently cited in publications featuring Sulfo-SBED in the label transfer application. The resulting easy-to-use kit also contains Streptavidin-HRP for subsequent detection of the biotinylated complex or biotinylated prey protein on a Western blot. •
Label transfer is an in vitro method for discovering or verifying an interaction that was observed by way of another technique such as the in vivo yeast 2-hybrid method or by in vitro methods such as co-immunoprecipitation or pull-down assays. • The label transfer method requires a purified "bait" protein. The amine groups of the bait protein are modified via the Sulfo-NHS moiety of Sulfo-SBED. This derivatized bait protein is then incubated in the dark with a lysate or with a purified putative "prey" protein. The bait and prey complex, if formed, is then captured or trapped by exposing the sample to high-intensity UV light, which activates the phenylazide moiety of Sulfo-SBED. This photoreactive group covalently links to the bound prey protein, capturing the interacting complex. Upon reduction of this complex, the biotin label that first resided with the bait protein transfers to the prey protein. The biotin label also functions as the detection target for the bait:prey complex or the prey protein upon Western blot analysis. The resulting biotin derivatized complex or prey protein can be detected using streptavidin-HRP or an anti-biotin antibody and chemiluminescent detection. The biotin label can also be used as a handle to purify the bait:prey complex over an avidin/streptavidin/NeutrAvidin/monomeric avidin biotin-binding protein support.
