Biomolecular Interaction Analysis

Get the accuracy, sensitivity and wide dynamic range you need for high-quality traditional biomolecular interaction analysis. Reichert’s Surface Plasmon Resonance (SPR) systems are designed to give you more — more flexibility, more choices, and more ways to advance your research.

  • Combine SPR with other techniques
  • Analyze crude samples and whole cells
  • Study protein-low molecular weight applications

All Major Classes of Biomolecules

Biomolecular interaction analysis involves interactions within and between:

  • Proteins
  • Nucleic acids (DNA/RNA)
  • Carbohydrates
  • Lipids

With Reichert SPR, you can characterize these interactions by determining the binding kinetics and affinity of the interaction of interest. These results let you relate structure to function, and understand complex biological pathways.

More Sensitive, More Accurate

Reichert SPR systems are highly sensitive, which allows you to work with very low immobilization levels — and therefore improve the accuracy of your results.

Antibody-Antigen Interactions

Differentiate antibody affinity and kinetics — and carry out epitope mapping.
