This Unit focuses on the technical and scientific management of Nuclear Magnetic Resonance (NMR) spectroscopy and molecular biophysics instrumentation available through the Structural Biology Programme. It provides CNIO researchers with equipment and experimental support for biophysical techniques used in studies of molecules involved in cancer. This includes the in vitro characterisation of i) the structure and dynamics of proteins using NMR and ii) the affinity and kinetics of protein interactions with other biopolymers and small molecules that could represent initial hits in drug discovery or research compounds for biophysical and functional studies. Furthermore, we use NMR to screen libraries of fluorinated fragments against macromolecular targets and to characterise the metabolic profiles of biofluids, cell growth media, and cell and tissue extracts from both animal models of cancer and human samples. The Unit is also endowed with a state-of-the-art, multiple-well microplate reader equipped with diverse detectors (absorbance; intensity, polarisation and time-resolved fluorescence; luminescence; and AlphaScreen) for in-solution and adherent cells measurements.
