5 + 4 =

The Surface Plasmon Resonance Microscopy (SPRM) system, integrates optical microscopy and SPR, is a powerful technique for measuring 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.

Features

Integrated optical microscopy with SPR Bright-field and SPR microscopies 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 delivery designs.

Analysis Modules include BI-DirectFlow™ Module for advanced five-channel ultra-fast kinetics research
