Biacore T200 Getting Started

At the concentrations of ligand commonly used for immobilization (20-200 µg/ml), the expected levels of immobilized ligand would be low in the absence of a mechanism that attract the ligand molecules to the sensor surface. The main mechanism for this concentration process is electrostatic attraction of the ligand to the surface.
