Overview of gel filtration and chromatography techniques for protein purification.

Illustration of gel filtration, ion-exchange, and antibody-affinity chromatography processes, showing protein separation based on size, charge, and antibody interaction.

This illustration presents a detailed comparison of gel filtration chromatography, ion-exchange chromatography, and antibody-affinity chromatography, highlighting how these methods separate and purify proteins. Gel filtration chromatography sorts molecules by size, ion-exchange chromatography separates them by charge, and antibody-affinity chromatography uses specific antibody interactions to isolate target proteins. The diagram shows the sequential process of sample loading, elution, and fraction collection.

This illustration is ideal for biochemistry education, molecular biology courses, research papers, and scientific journals focusing on protein purification techniques.
