The inQuiQ™ instrument using unique optical technology with ring-resonators for precise molecular binding measurements facilitates real-time, label-free analysis of biomolecular interactions. This white paper demonstrates the reusability and stability of the sensor chips. Effectiveness in repetitive analysis of biomolecule interactions is shown using rabbit IgG as ligand and anti-rabbit IgG as analyte. It highlights the instrument as a cost-effective and sensitive option for analysis of biomolecules, making advanced research on biomolecular interactions accessible for all.
