Beckman Coulter ProteomeLab XL-I analytical ultracentrifuge is equipped with absorbance (wavelength range 190 – 800 nm) and interference optics and can be used for both sedimentation velocity and sedimentation equilibrium experiments. Analytical ultracentrifugation is applicable for proteins, nucleic acids, lipids, polysaccharides, viruses and nanoparticles. It has a broad applicability including determination of sample homogeneity, oligomeric state of proteins (or molecular weight, respectively) and can be used to assess aggregation of sample and to study biomolecular interactions of self- and hetero-association systems (determination of stoichiometry and affinity).
Fully automated isothermal calorimeter AutoITC200 with ultrasmall working cell (200 µl). ITC method is used for characterization of biomolecular interactions of small molecules, proteins, antibodies, nucleic acids, lipids and others. Enzyme kinetics, biological activity or the effect of molecular structure changes on binding mechanism can be also assessed. Complete thermodynamic profile of the molecular interaction in a single experiment (stoichiometry, Ka, ∆H and ∆S values).
VP-ITC is isothermal calorimeter with 1400 µl volume of working cell. ITC method is used for characterization of biomolecular interactions of small molecules, proteins, antibodies, nucleic acids, lipids and others. Complete thermodynamic profile of the molecular interaction can be obtained in a single experiment (stoichiometry, Ka, ∆H and ∆S).

Biosensor system Octet utilizes BLI technology (biolayer interferometry) to detect the interaction parameters (kinetics, affinity) on a sensor chip. Octet RED96e enables simultaneous measurement of 8 channels ensuring high throughput. System is suitable especially for protein-protein or protein-nucleic acid interactions, however other binding systems can be evaluated as well.
Biacore T200 is a molecular interaction analysis system monitors real-time, label-free interaction ranging from ions to viruses. The system offers a powerful, versatile solution for obtaining the highest quality kinetic, affinity, concentration, specificity, selectivity, and thermodynamic data and can be used for multiple applications, from early research to drug discovery and development. In the arrangement, one of the interactants is immobilized on the sensor chip surface, while the other is passed over that surface in solution.
