Our services ensure accurate, objective, and reliable measurement results. We are committed to offering high-quality, one-stop technical services to meet the various experimental needs of our clients.

BLI Affinity Measurement: This is an optical analysis technique that measures changes in the thickness of the surface layer of a biomolecule fixed on a biosensor. When a target molecule interacts with the fixed molecule at the sensor’s surface, the change in quantity causes a corresponding change in the interference pattern, which is used to obtain information about the molecular interaction.

SPR Affinity Measurement: This method involves fixing one molecule on the surface of a sensor chip, while continuously flowing another molecule in solution over the chip. The detector can monitor the binding and dissociation of molecules from the chip’s surface in real-time. SPR records changes in the mass of molecules on the sensor chip's surface, providing real-time monitoring of molecular interactions.

Competitive ELISA Method for Measuring Affinity: A simple method for affinity measurement. Antibodies are mixed with antigens at different concentrations in an aqueous solution to reach equilibrium. Unbound antibodies are captured by antigens coated on a microplate and detected through the ELISA method.
