Protein Biophysical Characterization Service

With a wealth of knowledge on immunological interactions, we offer protein biophysical characterization services which can determine the kinetic characterization of protein-protein interactions. These services include determination of:

  • Affinity of protein-protein interactions
  • Association and dissociation rates of protein-protein interactions
  • Antibody-antigen specificity and affinity

PBL offers biophysical characterization of antibody affinity for a ligand or the measurement of antigen:antibody Kon/Koff rates. To accelerate assay development, we also determine which antibodies bind to antigens in a sandwich format. Binning— determination of antibodies which bind to non-overlapping epitopes—is performed using multiple hybridoma clones.

 

The graph to the right shows the association and dissociation of IFN to a surface-immobilized antibody using varying concentrations of IFN. The raw data is shown in blue and the model response in red.
