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.
