Biacore specializes in measuring protein-protein interaction and binding affinity. The technology is based on surface Plasmon resonance (SPR), an optical phenomenon that enables detection of unlabeled interactants in real time. The SPR-based biosensors can be used in determination of active concentration, screening and characterization in terms of both affinity and kinetics.
The presentation will describe recent progress of Biacore technology and highlight applications within drug discovery and development. This includes selection and detailed characterisation of the binding properties of biopharmaceuticals such as antibodies as well as new routes to find drug candidates based on small molecules. Here, Biacore is now used for compound fragment screening and with a throughput of 1400 fragments/day using only 10 ug of target protein. Information obtained includes the selectivity of binding and target site specificity that are important criteria in fragment selection. Not only affinities in the range from mM to pM can be measured but also the residence time (off-rate).
