Biophysical Service in Drug Discovery
Biophysical methods are widely used to understand binding kinetics, modes of action and the relationship between molecular structure and interactions. In recent years, biophysical assays have played an increasingly important role in drug discovery and development, particularly in the identification of lead compounds and the optimization of lead compounds. The importance of biophysics in drug discovery has been further enhanced with the development of a number of novel emerging technologies for the high-resolution determination of large numbers of biological structures and the characterization of combined kinetics and thermodynamics.
CD BioSciences has dedicated biophysicists who provide scientific services to our clients' integrated drug discovery programs through advanced technology platforms, including hit discovery methods for fragment-based lead discovery and complete mechanistic, structural, kinetic and thermodynamic analysis of our clients' compounds of interest. With an integrated biophysical platform, we provide our clients with accurate and real-time data for the analysis of molecular interactions and provide precise interpretation of the data to accelerate modern drug discovery.
