Protein purification principles

Affinity chromatography – principles

This is a powerful technique that separates proteins based on the reversible interaction between the target protein and binding substance (ligand).

Hydrophobic interaction chromatography principles

It separates biomolecules according to differences in their hydrophobicity.

Ion exchange chromatography – principles

Size exclusion chromatography – principles

Size exclusion chromatography, or gel filtration, is the simplest and mildest liquid chromatography technique.
