Theory of Affinity Chromatography

Theory of Affinity Chromatography

Theory of Affinity Chromatography describes selective binding of target molecules to ligands for precise separation. Loading/Binding Phase: The sample is introduced into a column with immobilized ligand. The target molecule binds specifically, while non-target molecules pass through. Washing Phase: Non-specifically bound molecules are removed using an appropriate buffer. Elution Phase: The target molecule is released … Read more
