Protein expression and purification
We have facilities for large-scale expression of recombinant proteins and access to several ÄKTA FPLC systems for protein purification.
Crystal screening and plate imaging
Our facilities have two robots for high-throughput crystal screening (Oryx 4 and Mosquito) and three crystallization hotels/imagers (Formulatrix RI-182, with capacity for 182 plates each) placed in temperature-controlled environments. Results can be accessed remotely in real-time though the RockMaker Web interface.
X-ray data collection
In-house X-ray diffraction data collection is possible with our Rigaku MacroMax 007 HF single crystal X-ray diffractometer. We also have regular access to leading international synchrotron radiation facilities such as ESRF (Grenoble), MAX IV (Lund) and DESY (Hamburg), coordinated by UiO for PX-Norway.
In addition, we offer services regarding protein crystal spectroscopy, processing of diffraction data and modeling upon request.
HDX-MS
State-of-the-art hydrogen-deuterium exchange mass spectrometer (HDX-MS, Waters-Synapt G2 Si): Mapping protein folding, conformational changes, protein-ligand and protein-protein interactions.
Biophysical characterization of proteins and protein interactions
A wide range of instruments for characterization of proteins is available at the Department of Medical Biochemistry, Oslo University Hospital. Our equipment includes:
- Microscale thermophoresis instruments (Monolith NT.LabelFree system and NT.115 system for labelled proteins): Quantitative analysis of protein-ligand interactions.
- Isothermal titration calorimeter (MicroCal iTC-200 micro-ITC): Quantitative analysis of protein-ligand and protein-protein interactions.
- Surface Plasmon Resonance (SPR) instrument (GE Biocore S200): Measurement of binding kinetics of protein-ligand and protein-protein interactions.
- Nano-differential scanning fluorimetry (nanoDSF) instrument (Nanotemper, Prometheus NT.48): Determination of thermal and chemical stability of proteins.
- Dynamic light scattering (DLS) system (Malvern Zetasizer Nano-ZS): Measurement of particle size and dispersity of protein solutions.
- SEC-MALS (Malvern Viskotek) : Determination of molecular weight of proteins during size-exclusion chromatography.
In-house SAXS
Small-angle X-ray scattering data can be collected with our Bruker Nanostar SAXS optimized for weak solution scattering, which is part of the RECX instrument park at the Department of Chemistry.
Neutron data collection
PX-Oslo has regular access to world-leading neutron scattering facilities such as the Institut Laue-Langevin (ILL, Grenoble) and the ISIS Neutron and Muon Source (UK).
