Abstract
Affinity chromatography is the method of choice for biomolecule separation and isolation with highly specific target recognition; it is ideally suited to the purification of immunotherapeutic proteins (i.e., mAbs). Conventional affinity purification protocols are based on natural immunoglobulin (Ig)-binding proteins, which are expensive to produce, labile, unstable, and exhibit lot-to-lot variability. Biological ligands are now being replaced by cost-effective, synthetic ligands, derived from the concepts of rational design and combinatorial chemistry, aided by in silico approaches. In this chapter, we describe a new synthetic procedure for the development of affinity ligands for immunoglobulins based on the multicomponent Ugi reaction. The lead ligand developed herein is specific for the IgG-Fab fragment and mimics Protein L (PpL), an IgG-binding protein isolated from Peptostreptococcus magnus strains and usually used for the purification of antibodies and their fragments.

Abstract
The global antibody market has grown exponentially due to increasing applications in research, diagnostics and therapy. Antibodies are present in complex matrices (e.g. serum, milk, egg yolk, fermentation broth or plant-derived extracts). This has led to the need for development of novel platforms for purification of large quantities of antibody with defined clinical and performance requirements. However, the choice of method is strictly limited by the manufacturing cost and the quality of the end product required. Affinity chromatography is one of the most extensively used methods for antibody purification, due to its high selectivity and rapidity. Its effectiveness is largely based on the binding characteristics of the required antibody and the ligand used for antibody capture. The approaches used for antibody purification are critically examined with the aim of providing the reader with the principles and practical insights required to understand the intricacies of the procedures. Affinity support matrices and ligands for affinity chromatography are discussed, including their relevant underlying principles of use, their potential value and their performance in purifying different types of antibodies, along with a list of commercially available alternatives. Furthermore, the principal factors influencing purification procedures at various stages are highlighted. Practical considerations for development and/or optimizations of efficient antibody-purification protocols are suggested.

Abstract
Synthetic affinity ligands can circumvent the drawbacks of natural immunoglobulin (Ig)-binding proteins by imparting resistance to chemical and biochemical degradation and to in situ sterilization, as well as ease and low cost of production. Protein L (PpL), isolated from Peptostreptococcus magnus strains, interacts with the Fab (antigen-binding fragment) portion of Igs, specifically with kappa light chains, and represents an almost universal ligand for the purification of antibodies. The concepts of rational design and solid-phase combinatorial chemistry were used for the discovery of a synthetic PpL mimic affinity ligand. The procedure presented in this chapter represents a general approach with the potential to be applied to different systems and target proteins.

Abstract
A novel affinity separation method in an aqueous two-phase system (ATPS) is suggested, using protein conjugated IgG as a ligand. For verification of the proposed approach, horseradish peroxidase (HRP) and human IgG was used as a ligand carrier and affinity ligand, respectively. The partition of the affinity ligand, human IgG, was controlled by the conjugation of HRP. Two ATPSs, one consisting of potassium phosphate (15%, w/w) and polyethylene glycol (PEG, M.W. 1450, 10%, w/w) and the other of dextran T500 (5%, w/w) and PEG (M.W. 8000, 5%, w/w), were used. The conjugated human IgG-HRP favored a PEG-rich top phase, whereas human IgG, rabbit anti-human IgG and goat anti-mouse IgG preferred a salt or dextran-rich bottom phase. Using the conjugated human IgG-HRP, rabbit anti-human IgG was successfully separated into a PEG-rich top phase from the mixture with goat anti-mouse IgG. The appropriate molar ratio between human IgG-HRP and rabbit anti-human IgG was around 3:1 and 1:1 for the salt and dextran-based ATPS, respectively. The dextran-based ATPS showed a better recovery yield and purity than the salt-based ATPS for the range of test conditions employed in this experiment. The yield and purity of the recovered rabbit anti-human IgG were 90.8 and 87.7%, respectively, in the dextran-based ATPS, while those in the salt-based ATPS were 78.2 and 73.2%.

Abstract
Many successful, recent therapies for life-threatening diseases such as cancer and rheumatoid arthritis are based on the recognition between native or genetically engineered antibodies and cell-surface receptors. Although naturally produced by the immune system, the need for antibodies with unique specificities and designed for single application, has encouraged the search for novel antibody purification strategies. The availability of these products to the end-consumer is strictly related to manufacture costs, particularly those attributed to downstream processing. Over the last decades, academia and industry have developed different types of interactions and separation techniques for antibody purification, affinity-based strategies being the most common and efficient methodologies. The affinity ligands utilized range from biological to synthetic designed molecules with enhanced resistance and stability. Despite the successes achieved, the purification "paradigm" still moves interests and efforts in the continuous demand for improved separation performances. This review will focus on recent advances and perspectives in antibody purification by affinity interactions using different techniques, with particular emphasis on affinity chromatography.

Abstract
A novel biomimetic ligand, N-benzyloxycarbonyl-l-tyrosine (N-cbz-l-Tyr), was screened by a combination method of molecular docking and immobilized receptor technique. Then, N-cbz-l-Tyr was immobilized on Sepharose CL-4B to prepare a specific affinity adsorbent for immunoglobulin G (IgG). Scatchard analysis of the binding isotherm for IgG on the adsorbent gave an association constant (K(a)) of 4.91 x 10(6) m(-1) and a theoretical maximum adsorption capacity of 17.3 mg IgG/mL gel. IgG with a purity of 98% was separated from human plasma by this new affinity adsorbent.

Abstract
The influenza virus surface glycoprotein antigen neuraminidase (NA) is a crucial viral enzyme with many potential medical applications; therefore, the development of efficient upstream and downstream processing strategy for the expression and purification of NA is of high importance. In the present work the NA gene from the H1N1 influenza virus strain A/Beijing/262/95 was cloned from viral RNA and expressed in expresSF+ insect cells using the baculovirus expression vector system (BVES). A limited affinity-ligand library was synthesized and evaluated for its ability to bind and purify the recombinant H1N1 neuraminidase. Affinity-ligand design was based on mimicking the interactions of the lock-and-key (LAK) motif (Phe-Gly-Gln), a common structural moiety found in the subunit interface of glutathione S-transferase I (GST I), and plays an important structural role in subunit-subunit recognition. Solid-phase combinatorial chemistry was used to synthesize 13 variants of the lock-and-key lead ligand (Phe-Trz-X, where X was selected alpha-amino acid) using the 1,3,5-triazine moiety (Trz) as the scaffold for assembly. One immobilized ligand, bearing phenylalanine and isoleucine linked on the chlorotriazine ring (Phe-Trz-Ile), displayed high affinity for NA. Absorption equilibrium and molecular modeling studies were carried out to provide a detailed picture of Phe-Trz-Ile interaction with NA. This LAK-mimetic affinity adsorbent was exploited in the development of a facile purification protocol for NA, which led to 335-fold purification in a single-step. The present purification procedure is the most efficient reported so far for recombinant NA.

Abstract
Thermosensitive poly(N-isopropylacrylamide)-based polymer particles were synthesised, and screened for the adsorption of human immunoglobulin G (hIgG). At pH 9 the adsorption on microgel particles was strongly affected by temperature, approximately 40 mg hIgG/g support (90% of initial hIgG) being adsorbed at 40 degrees C but only 10% of initial hIgG at 25 degrees C. At pH 5 the maximum adsorbed amount (20 mg hIgG/g support) was similar for both temperatures. The adsorption of hIgG on to charged poly(methyl methacrylate)/poly(N-isopropylacrylamide) core-shell latexes was negligible (5-10 mg hIgG/g support) at the same temperature and pH conditions. The lower adsorption of hIgG onto the core-shell particles is explained by steric interactions due to the small size of the shell.

Abstract
Affinity chromatography represents a promising technique for decoding the proteomics universe. While conventional affinity purification is being used in conjunction with two-dimensional electrophoresis (2D-PAGE) and mass spectrometry (MS) for the study of proteomes and subproteomes, scientists are still confronted with the need for specific and tailor-made affinity ligands to target desired groups and families of proteins. Evidence has shown that, in many situations, synthetic affinity ligands can circumvent inconveniences associated with the utilisation of biological ligands for the chromatography-based purification of biomolecules. This review will highlight the potential applications of affinity chromatography and synthetic de novo designed ligands as separation tools for proteomics.

Abstract
Affinity chromatography has the reputation of a more expensive and less robust than other types of liquid chromatography. Furthermore, the technique is considered to stand a modest chance of large-scale purification of proteinaceous pharmaceuticals. This perception is changing because of the pressure for quality protein therapeutics, and the realization that higher returns can be expected when ensuring fewer purification steps and increased product recovery. These developments necessitated a rethinking of the protein purification processes and restored the interest for affinity chromatography. This liquid chromatography technique is designed to offer high specificity, being able to safely guide protein manufactures to successfully cope with the aforementioned challenges. Affinity ligands are distinguished into synthetic and biological. These can be generated by rational design or selected from ligand libraries. Synthetic ligands are generated by three methods. The rational method features the functional approach and the structural template approach. The combinatorial method relies on the selection of ligands from a library of synthetic ligands synthesized randomly. The combined method employs both methods, that is, the ligand is selected from an intentionally biased library based on a rationally designed ligand. Biological ligands are selected by employing high-throughput biological techniques, e.g. phage- and ribosome-display for peptide and microprotein ligands, in addition to SELEX for oligonucleotide ligands. Synthetic mimodyes and chimaeric dye-ligands are usually designed by rational approaches and comprise a chloro-triazinlyl scaffold. The latter substituted with various amino acids, carbocyclic, and heterocyclic groups, generates libraries from which synthetic ligands can be selected. A 'lead' compound may help to generating a 'focused' or 'biased' library. This can be designed by various approaches, e.g.: (i) using a natural ligand-protein complex as a template; (ii) applying the principle of complementarity to exposed residues of the protein structure; and (iii) mimicking directly a natural biological recognition interaction. Affinity ligands, based on the peptide structure, can be peptides, peptide-mimetic derivatives (<30 monomers) and microproteins (e.g. 25-200 monomers). Microprotein ligands are selected from biological libraries constructed of variegated protein domains, e.g. minibody, Kunitz, tendamist, cellulose-binding domain, scFv, Cytb562, zinc-finger, SpA-analogue (Z-domain).

Abstract
The reversible phosphorylation of proteins regulates many biological processes. Despite the technological advances in the enrichment and detection of phosphorylated proteins, the currently available techniques still struggle with the complexity of the human proteome. The aim of this review is to highlight the molecular recognition elements of the interaction between phosphorylated proteins and peptides and pTyr or pSer/Thr-binding domains. The identification of the recognition features of the naturally occurring pTyr- and pSer/Thr-binding domains can contribute to an understanding of the molecular aspects of the affinity and specificity for phosphorylated residues. This might inspire the design of small "biomimetic" molecules with potential applications in assessing the extent of the phosphoproteome using affinity-based strategies.
