High Sensitivity NTA Sensors

OpenSPR High Sensitivity Sensors are made with a specialized nanogold surface to provide an extra boost of localized sensitivity close to the sensor surface. The increased localized sensitivity is particularly advantageous for small molecule analysis, and can also be used to enhance the signals of other larger biomolecules that interact close to the surface.

High Sensitivity NTA Sensors are used to capture biomolecules containing a His-tag onto the sensor surface for analysis in OpenSPR instruments. The reversible nature of the His-NTA interaction allows the ligand to be removed and re-immobilized for subsequent interaction analysis. Sensors are provided in a package of 8 or 3.

It is recommended to use with Nicoya's NTA Reagent Kit, which provides the surface preparation reagents (ie EDTA, NiCl2) as well as a ligand regeneration solution (imidazole) for required sample immobilization.

Note: High Sensitivity Sensors are only compatible with 2-Channel OpenSPR instruments.
