SPR biosensor studies provide direct binding information as well as real time kinetic data.

SPR is suitable for studying a wide range of systems and requires very low sample qualities due to the microfluidic components and is easily automated for handling larger sample sets. Assays can be tailored for the study of small molecule drugs as well as larger protein based analytes. The direct binding detection methods makes biosensor studies suitable for studying a interactions over an extremely wide dynamic range without the need for modifications to the assay conditions.
