METHOD OF MEASURING BINDING ACTIVITY OF LIGAND-BINDING PROTEIN HAVING POOR CHEMICAL STABILITY TO FIRST LIGAND

摘要

A method for assaying the binding activity of a first ligand to a chemically less stable ligand-binding protein, comprising immobilizing a second ligand that binds to the ligand-binding protein at a binding site distinct from the binding site of the first ligand to the ligand-binding protein, binding the protein to the second ligand, and then measuring the binding activity of the first ligand to the protein via surface plasmon resonance.
