A biotinylated human or murine derived phosphopeptide was immobilized onto a streptavidin-coated gold sensor chip for a surface plasmon resonance-based assay. On-rates were determined by applying an analyte solution of purified 6xHis tagged HACS1 SH3 domain or SHP1 N-SH2 domain at the indicated concentrations. Off-rates were determined by switching to an application of buffer alone at 120 s. Curve fits were made according to a 1:1 interaction model.
