SPR Assay Service

Surface Plasmon Resonance (SPR) is a biosensing analysis technology that utilizes the resonance between the extinction wave and the plasma wave of light in different media to construct a biosensing platform for detecting biomolecular interactions. It is used to detect the interaction between ligands and analytes on a biosensor chip.
