Property Technique Biorecognition (ligand specificity) Affinity chromatography Charge Ion exchange chromatography Size Gel filtration (sometimes called size exclusion) Hydrophobicity Hydrophobic interaction chromatography Reversed phase chromatography Fig. 1. Separation principles in chromatographic purification. Affinity chromatography separates proteins on the basis of a reversible interaction between a protein (or group of proteins) and a specific ligand coupled to a chromatography matrix. The technique offers high selectivity, hence high resolution, and usually high capacity for the protein(s) of interest. Purification can be in the order of several thousand-fold and recoveries of active material are generally very high. Affinity chromatography is unique in purification technology since it is the only technique that enables the purification of a biomolecule on the basis of its biological function or individual chemical structure. Purification that would otherwise be time-consuming, difficult or even impossible using other techniques can often be easily achieved with affinity chromatography. The technique can be used to separate active biomolecules from denatured or functionally different forms, to isolate pure substances present at low concentration in large volumes of crude sample and also to remove specific contaminants. Amersham Biosciences offers a wide variety of prepacked columns, ready to use media, and pre-activated media for ligand coupling.

Chapter 1 Affinity chromatography in brief Affinity chromatography separaes n the basis of reversibleinteraction between a protein(or group of proteins)and a specific ligand coupled to a chromatography matrix The technique is ideal for a capture or intermediate step in a purification protocol and can be used whenever a suitable ligand is available for the protein(s)of interest.With high selectivity, hence high resolution,and high capacity for the protein(s)of interest,purification levels in the order of several thousand-fold with high recovery of active material are achievable. Target protein(s)is collected in a purified,concentrated form. Biological interactions between ligand and target molecule can be a result of electrostatic or hydrophobic interactions.van der waals'forces and/or hydrogen bonding.To elute the target molecule from the affinity medium the interaction can be reversed,either specifically using a competitive ligand,or non-specifically,by changing the pH,ionic strength or polarity. In a single step,affinity purification can offer immense time-saving over less selective multi- nables plex biolog processed.Targe rom com ame substance ar For an even higher degree of purity,or when there is no suitable ligand for affinity purification, an efficient multi-step process must be developed using the purification strategy of Capture, Intermediate Purification and Polishing(Cp).When applying this strategy affinity chroma- tography offers an ideal capture or intermediate step in any purification protocol and can be used whenever a suitable ligand is available for the protein of interest. Successful affinity purification requires a biospecific ligand that can be covalently attached to a chromatography matrix.The coupled ligand must retain its specific binding affinity for the target molecules and,after washing away unbound material,the binding between the ligand and target molecule must be reversible to allow the target molecules to be removed in an active form.Any comp onent can be used as a ligand to ourify its respective binding .Enzymesubstrate analogue,inhibitor,cofactor. ·Antibody÷antigen,virus,cel.

9 Chapter 1 Affinity chromatography in brief Affinity chromatography separates proteins on the basis of a reversible interaction between a protein (or group of proteins) and a specific ligand coupled to a chromatography matrix. The technique is ideal for a capture or intermediate step in a purification protocol and can be used whenever a suitable ligand is available for the protein(s) of interest. With high selectivity, hence high resolution, and high capacity for the protein(s) of interest, purification levels in the order of several thousand-fold with high recovery of active material are achievable. Target protein(s) is collected in a purified, concentrated form. Biological interactions between ligand and target molecule can be a result of electrostatic or hydrophobic interactions, van der Waals' forces and/or hydrogen bonding. To elute the target molecule from the affinity medium the interaction can be reversed, either specifically using a competitive ligand, or non-specifically, by changing the pH, ionic strength or polarity. In a single step, affinity purification can offer immense time-saving over less selective multistep procedures. The concentrating effect enables large volumes to be processed. Target molecules can be purified from complex biological mixtures, native forms can be separated from denatured forms of the same substance and small amounts of biological material can be purified from high levels of contaminating substances. For an even higher degree of purity, or when there is no suitable ligand for affinity purification, an efficient multi-step process must be developed using the purification strategy of Capture, Intermediate Purification and Polishing (CIPP). When applying this strategy affinity chromatography offers an ideal capture or intermediate step in any purification protocol and can be used whenever a suitable ligand is available for the protein of interest. Successful affinity purification requires a biospecific ligand that can be covalently attached to a chromatography matrix. The coupled ligand must retain its specific binding affinity for the target molecules and, after washing away unbound material, the binding between the ligand and target molecule must be reversible to allow the target molecules to be removed in an active form. Any component can be used as a ligand to purify its respective binding partner. Some typical biological interactions, frequently used in affinity chromatography, are listed below: • Enzyme substrate analogue, inhibitor, cofactor. • Antibody antigen, virus, cell. • Lectin polysaccharide, glycoprotein, cell surface receptor, cell. • Nucleic acid complementary base sequence, histones, nucleic acid polymerase, nucleic acid binding protein. • Hormone, vitamin receptor, carrier protein. • Glutathione glutathione-S-transferase or GST fusion proteins. • Metal ions Poly (His) fusion proteins, native proteins with histidine, cysteine and/or tryptophan residues on their surfaces
