Abstract:
Computer simulation of affinity chromatography is a valuable tool for accurate prediction of column performance. In our study affinity pairs based on lectin and antibody interactions with carbohydrates have been used as model systems. In this well-characterized system we have demonstrated the usefulness of the simulation approach for determination of affinity and kinetics. These properties are typically difficult to obtain for many weakly interacting molecular species (i.e., when dissociation constants (K(D)) are greater than 10(-5) M). The influence of affinity and kinetics on peak broadening in affinity chromatography has also been investigated.

Protein-Drug Binding: Determination Methods
Indirect methods involve isolating the bound drug from its free form in biological samples such as blood, serum, or plasma. These techniques aim to measure the percentage of drugs bound to proteins. Equilibrium dialysis is a commonly used method where the free drug concentration at equilibrium is measured by separating the bound...
