SOUHLAS
Course Enrolment Limitations
The course is offered to students of any study field.
Course objectives
The students will learn about the aspects of biomolecular interactions, their significance and biological relevance, and they will get an overview of both traditional and state-of-art methods for the study of biomolecular interactions.
Learning outcomes
At the end of the course students should be able to: understand and explain principles of thermodynamics and kinetics of biomolecular interactions; understand thermodynamics of binding, interpret binding curves make reasoned decisions about selecting a proper method for particular applications
Syllabus
  • 1. Introduction to Biomolecular interactions (significance, biological relevance, equilibrium, association and dissociation constants, kinetics). Types of interactions (hydrophobic, coulombic, hydrogen bonds, van der Waals forces). 2. Classical versus modern methodology Classical methods for characterization of interactions (equilibrium dialysis, frontal chromatography). Direct measurement of complex formation (change in absorbance, fluorescence intensity, fluorescence polarization). Surface plasmon resonance (theoretical background, comparison with ELISA methods). 3. Thermodynamics of protein-ligand interactions Thermodynamics of binding (Gibbs free energy, enthalpy, entropy). Macroscopic and microscopic views. The pH and temperature dependence of complex formation. Entropy-enthalpy compensation. Isothermal titration calorimetry (theoretical background, measurement of high-affinity and low-affinity interactions. displacement measurement, single-injection measurement, comparison with other methods, limits of ITC, possible problems. 4. Oligomerization and protein-protein interactions. Protein stoichiometry, stereochemistry. Protein folding (hydrophobic effect, hydrophilic interactions, hydrogen bonds, electrostatic forces, water molecules). Subunit-subunit interactions (electrostatic and shape complementarity). Protein-protein recognition sites. Determination of oligomerization (cross-linking, analytical ultracentrifugation). 5. Microscale thermophoresis (MST) – theoretical background, labelling and assay development, determination of Kd and stoichiometry, applications 6. Characterization of interactions on cell level. Possibility of whole cell assay within SPR and ITC. Modeling of native conditions (sensor chip versus in-solution measurement). Haemagglutination. 7. Importance of sample preparation („garbage in, garbage out“), methods for sample quality determination.
