McGill SPR Facility
For applications including proteomics, drug discovery, immunogenicity, and food analysis, state-of-the-art Surface Plasmon Resonance (SPR) technology allows for label-free, real-time biomolecular interaction analysis. Using purified preparations or complex mixtures, binding interactions between proteins, lipids, carbohydrates, nucleic acids, small molecules, and cells/viruses can be examined quantitatively in their native state with low sample consumption. In a typical experiment, the ligand (‘bait’) is immobilized to a gold-plated sensor chip and repeated injections of analyte (binding partner ‘target’) are then flowed overtop. A variety of sensor chip surfaces (eg. dextran, streptavidin, antibodies) and immobilization chemistries (eg. amine, capture, thiol) are available to tailor each project. Analyte-ligand association and dissociation events are monitored by changes in molecular mass accumulation at the solid-liquid interface on the sensor chip surface. The acquired data can answer questions regarding binding specificity, stoichiometry, concentration, kinetics (ka, kd), thermodynamics, and overall affinity (KD=kd/ka). To discover novel interaction partners, unknown binding candidates can also be recovered from cellular/tissue lysates for subsequent identification by Mass Spectrometry (SPR-MS ligand fishing). As described at www.biacore.com, our facility is equipped with two BIACORE 3000 systems.
