Rebecca L. Rich is a Senior Research Scientist at the Center for Biomolecular Interaction Analysis at the University of Utah. Determination of interaction kinetic constants for HIV-1 protease inhibitors using optical biosensor technology. Instead of screening many compounds against an immobilised target, these researchers pan one target against thousands of compounds spatially resolved on a surface. This information is particularly useful when identifying the roles that specific functional groups, both within the target as well as within a compound, play in binding. Surface Plasmon Resonance's impact on drug discovery - resolution, throughput and versatility By Dr David G. Myszka and Dr Rebecca L. Rich Surface plasmon resonance (SPR) biosensors have rapidly become a standard tool within the pharmaceutical and biotechnology industries. One approach to implementing biose nsor technology in high-throughput screening involves the application of array-based biosensor technology. Since 1992, CHI has been offering the life sciences community specialized information through its conferences and integrated portfolio of products and has produced over 500 conferences attracting more than 50,000 attendees from around the world ranging … 15 Frostell-Karlsson, A et al (2000). Recognit. The epitope specificity of an antibody is an innate property that cannot be designed rationally. SPR is an optical phenomenon that involves the transfer of light waves (photons) into electron waves (plasmons) at a thin metal layer. 300: 132-138. In addition, SPR has been successfully applied to drug discovery ligand-fishing and clinical immunogenicity studies (i.e., to monitor an immune response against a therapeutic agent). Implementing surface plasmon resonance spectroscopy in drug discovery. & Biol. Weekly e-newsletter, a round-up of the most interesting and pertinent industry news and developments. Improving biosensor analysis. We use cookies to provide you with a better experience, read our Cookie Policy, Industry Insight Aug 30, 2018 The result is an instrument that is capable of monitoring molecules with masses less than 90Da binding directly to macromolecular targets (8). In addition, current ADME tests are themselves laborious, time-consuming and expensive. Recognit. It is perhaps fortuitous that SPR biosensors became available at the same time that production of recombinant proteins began in earnest. (eds) Ligand-Macromolecular Interactions in Drug Discovery. Surface plasmon resonance (SPR)—label-free, biosensor-based systems—have been widely used to study bimolecular interactions in real time, and have come to be regarded as a … Q: Do you envisage researchers using the SierraTM SPR-32 system alongside their mass spectrometry systems? Unlike pull-down assays based on plates, beads, or filter binding, biosensors can detect the amount of complex formed in the presence of free material. In: Roque A. Surface Plasmon Resonance (SPR) spectroscopy, a technology developed 25 years ago, is now the gold standard technique for the study of biomolecular interactions for a wide variety of analytes – from small molecules in drug discovery to peptides, proteins, viruses and even nano-particles. The types of molecules that can be characterized are diverse, from ions and fragments to proteins and viruses. SPR is used extensively throughout the early drug discovery process from fragment screening to hit prioritization to lead optimization. SPR instruments are primarily used to measure the binding kinetics and affinity of molecular interactions. 15: 352-376. Plasmon waves are sensitive to the refractive index of the medium near the surface through which they travel. Anal. In fact, it’s hard to identify another technology that can be implemented in so many aspects of the drug discovery process. HSA or AGP) creates a profile of binding behavior. Highresolution and high-throughput protocols for measuring drug/human serum albumin interactions using BIACORE. Anal. Conclusion: SPR was as effective as MOX in combination regimens with RIF and PZA. He has also developed novel biosensor data processing and analysis programmes and published more than sixty articles describing the technology’s diverse applications. J. Pharm. The upper limit for the association kinetics is controlled by the diffusion rate of an analyte to its binding partner immobilised on the biosensor surface. Knowing how fast a molecular complex forms and breaks down is essential, particularly in structure/activity relationship (SAR) studies. Commonly used Biacore 2000 and 3000 platforms are capable of running 100 to 200 independent assays per day, depending on the experimental conditions. Structurally related compounds are arrayed within specific patterns on the chip so that a significant amount of SAR information is acquired from the primary screen.
