Surface Plasmon Resonance

Biosensing Instrument Incorporated is devoted to providing high-performance Surface Plasmon Resonance (SPR) instruments for creative research and efficient analysis. Using innovative designs, their instruments offer high sensitivity for detecting analytes of various sizes, a wide time response range for slow and fast kinetics, and maximum versatility and flexibility.

Applications Include:

  • Gene assays (e.g., single nucleotide polymorphism) and DNA/DNA interactions
  • Immunosensing (ligand-receptor, antibody-antigen, etc.)
  • DNA/protein, protein/protein and protein/drug interactions
  • Protein unfolding and conformational changes
  • Drug discovery and development

SPRm 200 Surface Plasmon Resonance Microscopy System

Simultaneous optical imaging with SPR measurements.

• The Surface Plasmon Resonance Microscopy (SPRM) system integrates optical microscopy and SPR to offer a powerful technique for measuring the binding activities of membrane proteins in vitro. It allows the simultaneous measurement of phenotypical changes of the sample via bright field and binding strength and kinetics via SPR.

• Integrated optical microscopy with SPR Bright-field and SPR microscopy in one instrument. Large field of view with high resolution optics to view single or multiple cells

• In vitro and label-free binding activities mapping Provides SPR sensorgrams and binding activity map of individual cells as well as the binding kinetic constants (ka, kd, KD)

• Nanometer scaled binding response of virus, bacteria and nanoparticles Nanomotion detection study of bacteria or virus metabolic activity or binding activities of nanoparticles for drug
