Affinity Measurement Services

Affinity is a characteristic parameter to evaluate the strength of the interaction between two molecules in the process of reversible reaction. It is an important indicator to understand molecules, identify biological processes, and discover and screen drugs. It is of great significance in early drug research and development, screening and identification, as well as quality control in downstream production, and is also widely used in basic research of life science, biopharmaceutical development and other fields.

KMD Bioscience has been committed to the study of interaction between biomolecules for many years, and our scientific experts have accumulated many years of experience in interaction research and detection. With rich technical experience, we can provide customers with high-quality affinity measurement services. We insist on fine control of each step of experiments to ensure the smooth progress of customers' experiments. At the same time, the company has a rich product pipeline, which can realize the qualitative and quantitative analysis of protein, antibody and Fab fragment interactions.
