Surface Plasmon Resonance (SPR)

Powerful services for your biomolecular interaction research, SPR monitors binding events in real time by detecting shifts in the refractive index at a sensor's surface.

SPR Capabilities & Applications

Complete Kinetic &
Affinity Profiling

Precisely determine binding kinetics
(ka, kd) and affinity (KD) to quantitatively characterize biomolecular interactions.

Antibody Half-life
Ranking Panel

Utilize FcRn binding panel to analyze pH-dependent interactions, enabling 
to forecast the in vivo half-life of your antibody candidates.

Custom Assay
Development

Design novel, project-specific SPR methodologies to address unique research challenges or non-standard interactions.
