Factors affecting protein drug binding
WebFactors Affecting Protein-Binding of Drugs ... Effect of protein binding on elimination of drugs Protein binding decreases the renal excretion of drugs and enhances the biological half-life. Only the free drug can get … WebBinding affinity is the strength of the binding interaction between a single biomolecule (e.g. protein or DNA) to its ligand/binding partner (e.g. drug or inhibitor). Binding affinity is typically measured and reported by the equilibrium dissociation constant (K D ), which is used to evaluate and rank order strengths of bimolecular interactions.
