SPR imaging for high throughput, label-free interaction analysis.

Author information

Institute for Systems Biology, Seattle, Washington 98103, USA.


Surface plasmon resonance (SPR) sensors have proven themselves over the last 20 years to be an effective method to study biomolecular binding and kinetics without the use of labeling. More recently, the approach has been adapted to high-throughput use with the imaging of SPR-active microarrays. This is an excellent tool for monitoring microarray binding in real-time where the microarray probes and targets can include a wide range of molecules. DNA, RNA, antibodies, enzymes, and a range of other proteins have been arrayed and quantitatively analyzed.
