Flow Channel SPR System Bio-REX SPR300F

This is the research and analytical system which can calculate the bind reaction velocity of various biological molecules by using surface plasmon resonance.

Main Use

  • Research of antigen antibody reaction
  • Drug screening
  • Research of binding properties of receptor and ligand

Measurement Principle

Measurement principle

When light is totally reflected on the surface of vacuum‐deposited gold films, incident light of resonance angle is absorbed by surface plasmon resonance (SPR), then dark line is generated in the reflection light.

By monitoring the subtle changes of dark light, the binding and dissociating states of the molecules on the gold film can be detected in real time.


  • Software for calculating each binding rate constant is included as a standard. The speed of binding and dissociation reaction can be calculated by each rate constant.

Reaction with quick binding and dissociation / Reaction with slow binding and dissociation

  • Minute amounts of sample liquid (more than 30ul) also can be detected by adopting parallel microfluidic SPR-system.
