Molecular interaction analysis


  • Surface Plasmon Resonance (SPR), real time and label-free interaction analysis.

Range of services

  • Set up for every pair of molecules: optimization of the ligand immobilization (way and density to be immobilized), reference channel, buffer running and temperature.
  • Optimization of strategies to obtain the best results in accordance the source of the samples: qualitative or quantitative perspectives.
  • Evaluation of the rates constants (kon, koff) and equilibrium constants (KA, KD) in different models: protein/DNA, protein/protein, protein/peptide, carbohydrate/protein, RNA/DNA.
  • Screening of lead candidates in drug discovery.
  • Evaluation of the association and dissociation rates and the half-life complex measurements.
  • Thermodynamic analysis.

Examples of application

  • Determination of the binding domain for the analysis of different mutants against targets.
  • Effect of cofactors, metal ions and other molecules against the binding kinetics.
  • Toxin detection.
  • Characterization of immune response.
  • Effect (in kinetics terms) of different modifications of antibodies.


  • Biacore T200 (GE)
