AFFINIX QN sensor

The stick-type sensor for AFFINIX QN is made by a 27 MHz quartz crystal and a ceramic support. This sensor is resistible for organic-solvent, general organic-solvent is applicable for immobilization of samples. Standard surface of sensor is gold that is versatile surface for immobilization of biomolecules, we have many immobilization protocols of molecules and blocking protocols of non-specific bindings. We can offer special sensor surface (e.g. SiO2, TiO2 coating) upon your request, please contact us.

  • Stick-type sensor assembled with ceramic support and quartz crystal sensor.
  • AFFINIX QN sensor
    Standard gold surface
  • Metal Oxides coating sensors (e.g. SiO2, TiO2)
  • Immobilization protocols and services of molecules

Application

  • Non label, real time monitoring for molecular recognition or reaction monitoring
  • Comparing experiments (specific or nonspecific ligand, analyte concentration, buffer condition, temperature. etc.)
  • Build up the experimental procedures
  • Aggregation monitoring
  • Evaluation of polymer, thin film, nanoparticle, nanotube and other nanomaterials
  • Interaction analysis between many molecules
  • Long time measurement
  • Analysis of binding constant (dissociation constant) and kinetic parameters
  • Measurements in crude solution

Software (AQUA)

For AFFINIX series measurements, we provide the analytical software that enable to do following analysis easily.

  • Equilibrium analysis (binding constant (Ka) and dissociation constant (Kd))
  • Kinetic analysis (binding rate (kon) and off rate (koff))
