Measurement of Affinity Constants
The Biophysics Unit is equipped with instruments designed to determine the strength and biophysical properties of macromolecular or protein-ligand interactions, including association and dissociation constants, as well as stoichiometry of binding. Available techniques include isothermal titration calorimetry, microscale thermophoresis, and bio-layer interferometry (which can also be utilized for quantifying known components in complex mixtures).
Characterisation of Macromolecular Samples
Structural biology and biochemical assays often require sample optimization to achieve stability and homogeneity, while understanding the oligomerisation state and precise composition of macromolecular complexes is crucial for unravelling their architecture. To address these needs, the Biophysics Unit offers a service leveraging various instruments to determine the molecular weights of species in solution and their thermal stability parameters. Techniques utilized include mass photometry, SEC-MALS, dynamic light scattering, and nanoDSF.
