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

Introduction of Affinity Chromatography Introduction of Affinity Chromatography explains separation of biomolecules based on specific binding interactions. Introduction Affinity Chromatography is a liquid chromatography technique that separates molecules based on specific and reversible interactions between a molecule in a mixture and a counter-molecule bound to a stationary phase. It is extensively used in biochemistry and … Read more
