Biotinylation protocol
WebThe protocol described below ( 7, 8) uses a water-soluble analog of N -hydroxylsuccinimide biotin (Pierce, Rockford, IL), which can be dissolved directly in the reaction buffer. Biotin-coupled antibodies are stable under normal storage conditions. 2 Materials 1. IgG. 2. Sulfosuccinimidobiotin: 2 mg/mL in sodium borate buffer ( see Note 1 ). 3. WebProcedure for Pull-Down Biotinylation Protein:Protein Interaction Assay A. Immobilized Streptavidin Preparation The bait protein must have been already purified, biotinylated and the complex removed of nonreacted biotinylation reagent before beginning this procedure. See Appendix E for a list of suggested biotinylation reagents. 1.
