The aim of this study was to compare the affinity values obtained for a monoclonal antibody/antigen complex using two different techniques, surface plasmon resonance (SPR) and an enzyme linked immunosorbent assay (ELISA) approach recently described by Bobrovnik S.A. and by Stevens F.J. The system is used to deliver high-quality kinetic, binding affinity, concentration, specificity, selectivity, and thermodynamic interaction data, all with high sensitivity. Based on Surface Plasmon Resonance (SPR) technology, the Biacore T200 system significantly enhances performance so that the upper and lower limits of kinetic ranges can be assessed. The measured binding affinity of cholera toxin for the ganglioside sequence ranges from 4.61 x 10-12 M for GM1 to 1.88 x 10-10 M for asialo GM1. The picomolar values obtained by surface plasmon resonance are similar to Kd values determined with whole-cell binding assays.
After processing the chip and two others with a deactivated SHP1358 and a deactivated ComS (and Rgg-like protein), the figure below was created. We previously used this strategy with an in vitro competitive surface plasmon resonance method that relied on high-affinity antibody fragments to obtain RAS-binding compounds.
