Electron Paramagnetic Resonance (EPR)-based methods have been used to map local dynamic and structural features of biomolecules, to explore different modes of biomolecule-ligand interaction, to obtain long-range structural restraints and to probe metal-ion-binding sites.
Our EPR instrument con be used either in Continuous-wave X-Band or Continuous-wave/Pulse Q-Band configurations. EPR measurements can be performed on biological samples containing paramagnetic metal ions (i.e. Fe, Cu, Mn etc.) or free radicals, or on samples that have been labelled with paramagnetic tags (e.g. spin labels). The pulse Q-band EPR instrumentation present at CERM/CIRMMP can be used to measure ESEEM, HYSCORE, ENDOR and DEER experiments.
EPR spectra can be recorded at different temperatures, between room temperature down to 4K. For cryogenic conditions, including pulsed Q-band measurements, samples must be previously frozen, ideally in a glassing state. For aqueous samples, 40%-10% v/v glycerol or EG, or ~0.4 M sucrose, or other sugars like trehalose can be used as a glassing agent.

Relaxometry is a technique that has been developed to obtain structural and dynamical information on nuclear spin systems. In the presence of a paramagnetic metal ion in the compound under investigation, relaxometry may provide information on the coordination of the nuclear spin with respect to the paramagnetic metal and, indirectly, information on the electron spin system. In fact, if the water proton exchange rate is fast or of the same order as the NMR timescale, the magnetic properties of the paramagnetic center are carried over from the water in bound position to the bulk.

Biocenter Oulu Molecular Biophysics core facility offers multiple technologies for analysing secondary structure and stability of biological macromolecules, biomolecular interactions and enzyme kinetics.
Techniques are available for the analysis of kinetic and thermodynamic parameters of biomolecular interactions and for the biophysical characterisation of the structure, function and stability of biological biological macromolecules like proteins, nucleic acids, lipids and their complexes.
The HT Robotein® facility at CIP and SBBC has the particularity to combine high technology laboratory instrumentation: a central liquid handling workstation, a colony picking instrument, various microplate spectrophotometers, an Octet HTX, a LabChip GXII, a protein spotter and an Infrared Imager. This specific combination of equipment offers versatile tools for the development of numerous HT applications. Here is a list of the main services that Robotein® can provide. Nonetheless, we are always open to develop new and innovative assays.
The combination of the central liquid handling platform with the microplate spectrophotometers offers the possibility to analyse in an automated and HT manner the conformational stability (△G0) of proteins in the presence of chaotropic agents (e.g. urea, guanidinium chloride).
Furthermore, a direct link can be created to build a protein array from hundreds of different proteins or proteins that have been submitted to different conditions. A unique combination of a HT protein arrayer (using 96 or 384 –well plates) and a state-of-the-art infrared imager allows hundreds of proteins to be quantitatively analysed in a few minutes for secondary structure, phosphorylation, glycosylation or any contaminant of known infrared spectrum.
The central robotic workstation linked to the Octet HTX instrument (fortéBio), enables real-time and label-free determination of binding affinity (Equilibrium dissociation constant: Kd) by measuring kinetics of association and dissociation of the complex (kon, koff). Using microtiter plates as liquid sample holders, the system can measure up to 96 samples in parallel. The Octet HTX is highly modular and can be easily adapted to measure interactions for a large range of antibodies, proteins, peptides or small molecules.
The combination of the central robotic workstation with the Octet HTX instrument (fortéBio) can also be used to perform fast and accurate protein quantitation from crude extracts (cell extracts, culture media, etc.), with no required purification steps. This method is particularly suitable to measure the concentration of full-length antibodies or various antibody fragments (although the modularity of the Octet system makes it compatible for the quantitation of many other proteins or peptides).
The combination of the central robotic workstation with a microplate spectrophotometer allows for the development of fully automated, easy, fast and robust enzymatic assays. For instance, we have performed automated quantification (i.e. determination of the relevant kinetic parameters: kcat, Km, and kcat/Km) of carbohydrate-isomerases, several dehydrogenases and various β-lactamases.
Using the central robotic workstation together with the microplate spectrophotometer and a quantitative PCR block, we developed protocols for automated screening of 164 buffers/pH conditions to improve protein stability and activity. This screen covers a pH range from 2 to 10, in 19 different buffers that are the most commonly used by pharmaceutical companies. This screen is coupled to HT and automated Differential Scanning Fluorimetry (DSF) thermal shift assays and enzymatic/binding affinity measurements in order to determine the best buffer/pH conditions that are compatible with the protein optimum stability and activity. We have validated this screen with several hydrogenases, oxygenases, ß-lactamases and antibody fragments.
We developed an automated screen of 96 refolding conditions for protein expressed as inclusion bodies. This screen, coupled to HT enzymatic/binding activity measurements, offers the possibility to significantly improve the refolding yield of active protein from inclusion bodies in a fast and reproducible manner.

Biocomplex is specialized in macromolecular sample preparation and purification for functional and structural studies using preparative ultracentrifugation, monolithic chromatography and asymmetrical flow field-flow fractionation technologies. Biocomplex also actively develops new purification methods for large biopolymers, often in co-operation with manufacturers. Our technologies can be used in different combinations to purify large macromolecular complexes such as viruses, virus-like particles, viral subassemblies, exosomes, membrane vesicles, large protein complexes, and ribonucleoprotein complexes as an important first step in the structure analysis pipeline. Samples produced at Biocomplex can be further studied at the CryoEM facility located in the same building (see Electron Microscopy, Helsinki). We accept both visits and shipped samples. Please contact grp-biocomplexservice@helsinki.fi for enquiries.
