Abstract
The purification of the product, the so-called downstream process (DSP), tends to be one of the most costly aspects of modern bioprocessing, especially in the case of proteins. In such cases, chromatography is still the major tool on all levels of the DSP from the first capture to the final polishing step. In this chapter, we will first outline the commonly used methods and their setup, in particular ion exchange chromatography (IEX), hydrophobic interaction chromatography (HIC), affinity chromatography (AC), and gel filtration (GPC, SEC), but also some less-known alternatives such as hydroxyapatite chromatography (HAC). Then the rational design of a downstream process, which usually comprises three orthogonal chromatographic steps, is discussed. Finally, process variants deviating from the usual batch-column/gradient elution approach will be presented, including expanded bed, displacement, and continuous chromatography, but also affinity precipitation. A most recent trend observable in the biotechnical DSP is the drive towards disposable elements (single-use technologies). Some options for this will be discussed as well.

Abstract
Defining membrane proteomes is fundamental to understand the role of membrane proteins in biological processes and to find new targets for drug development. Usually multidimensional chromatography using step or gradient elution is applied for the separation of tryptic peptides of membrane proteins prior to their mass spectrometric analysis. Displacement chromatography (DC) offers several advantages that are helpful for proteome analysis. However, DC has so far been applied for proteomic investigations only in few cases. In this study we therefore applied DC in a multidimensional LC-MS approach for the separation and identification of membrane proteins located in cholesterol-enriched membrane microdomains (lipid rafts) obtained from rat kidney by density gradient centrifugation. The tryptic peptides were separated on a cation-exchange column in the displacement mode with spermine used as displacer. Fractions obtained from DC were analyzed using an HPLC-chip system coupled to an electrospray-ionization ion-trap mass spectrometer. This procedure yielded more than 400 highly significant peptide spectrum matches and led to the identification of more than 140 reliable protein hits within an established rat kidney lipid raft proteome. The majority of identified proteins were membrane proteins. In sum, our results demonstrate that DC is a suitable alternative to gradient elution separations for the identification of proteins via a multidimensional LC-MS approach.

Abstract
Displacement chromatography has several advantages over the nonlinear elution technique, as well as the linear elution mode, such as the recovery of purified components at high concentrations, less tailing during elution, high throughput and high resolution. Displacer affinity and its utilization are the critical components of displacement chromatography. Particularly, the nonspecific interactions between the displacer and the stationary phase can be exploited to generate high affinity displacers. This chapter will discuss the design and execution of displacer selection and implementation in a separation specifically focusing on its utilization in ion exchange chromatography.

Abstract
Chemoenzymatic parallel synthesis and high-throughput screening were employed to develop a multivalent aminoglycoside-polyamine library for use as high-affinity cation-exchange displacers and DNA-binding ligands. Regioselective lipase-catalyzed acylation, followed by chemical aminolysis, was used to generate vinyl carbonate and vinyl carbamate linkers, respectively, of the aminoglycosidic cores. These were further derivatized with polyamines, leading to library generation. A parallel batch-displacement assay was employed to identify the efficacy of the library candidates as potential displacers for protein purification. Using this approach, low-molecular-mass displacers with affinities higher than those previously observed have been identified. The aminoglycoside-polyamine library was also screened for DNA binding efficacy using an ethidium bromide displacement assay. These highly cationic molecules exhibited strong DNA-binding properties and may have potential for enhanced gene delivery.

Abstract
The overall topic of the investigation was the separation of basic proteins by cation exchange displacement chromatography. For this purpose two principal column morphologies were compared for the separation of ribonuclease A and alpha-chymotrypsinogen, two proteins found in the bovine pancreas. These were a column packed with porous particles (Macro-Prep S, 10 microm, 1000 A) and a monolithic column (UNO S1). Both columns are strong cation exchangers, carrying -SO3(-)-groups linked to a hydrophilic polymer support. Poly(diallyl-dimethylammonium chloride) (PDADMAC), a linear cationic polyelectrolyte composed of 100-200 quaternary pyrrolidinium rings, was used as displacer. The steric mass action (SMA) model and, in particular, the operating regime and dynamic affinity plots were used to aid method development. To date the SMA model has been applied primarily to simulate non-linear displacement chromatography of proteins using low molar mass displacers. Here, the model is applied to polyelectrolytes with a molar mass below 20000 g mol(-1), which corresponds to a degree of polymerization below 125 and an average contour length of less than 60 nm. The columns were characterized in terms of the adsorption isotherms (affinity, capacity) of the investigated proteins and the displacer.

Abstract
Parallel batch screening experiments were carried out to examine how displacer chemistry and salt counterions affect the selectivity of batch protein displacements in anion exchange chromatographic systems. The results indicate that both salt type and displacer chemistry can have a significant impact on the amount of protein displaced. Importantly, the results indicate that, by changing the displacer, salt counterion, or both, one can induce significant selectivity changes in the relative displacement of two model proteins. This indicates that highly selective separations can be developed in ion exchange systems by the appropriate selection of displacer chemistry and salt counterion. The experimental batch screening data were also used in conjunction with various molecular descriptors to generate quantitative structure efficacy relationship (QSER) models based on a support vector machine feature selection and regression tool. The models resulted in good correlations and successful predictions for an external test set of displacers. A star plot approach was shown to be a powerful tool to aid in the interpretation of the QSER models. These results indicate that this modeling approach can be employed for the a priori prediction of displacer efficacy as well as for providing insight into displacer design and the selection of proper mobile-phase conditions for highly selective separations.

Abstract
In this paper, the selectivity of a variety of cation-exchange stationary phases was investigated using a homologous series of displacer molecules based on pentaerythritol. These displacers were derived from pentaerythritol and contained either four trimethyl ammonium groups [pentaerythrityl-(trimethylammonium chloride)4, PE(TMA)4], benzene rings [pentaerythrityl-(benzyl dimethylammonium chloride)4, PE(DMABzCl)4], heptyl groups [pentaerythrityl-(heptyl dimethylammonium iodide)4, PE(DMAHepI)4] or cyclohexyl groups [pentaerythrityl-(cyclohexyl dimethylammonium iodide)4, PE(DMACyI)4]. This series enabled us to probe the secondary interactions that can play a role in the affinity of low-molecular-mass displacers for different stationary phases. The relative affinities of these displacers were examined using a displacer ranking plot based on the steric mass action (SMA) isotherm model. While hydrophobicity and aromaticity played important roles in generating the affinity to the hydrophilized polystyrene-divinylbenzene (Source 15S) and polymethacrylate-based (Toyopearl 650M) resins, these secondary interactions had a minimal impact on the selectivity in agarose resins coated with dextran (SP Sepharose XL), "gel in a shell" (S Ceramic HyperD F), and monolithic (Bio-Rad Uno S6) cation-exchange materials. Further, the results with a tentacular stationary phase (Fractogel EMD) suggest that the alkyl chains on PE(DMAHepI)4 play an important role in increasing the affinity, possibly because of strong interactions between the alkyl moiety and the polymer matrix as well as between the charged groups and the polyelectrolyte tentacles. The results of this study provide insight into the design of high affinity, low-molecular-mass displacers for different cation-exchange stationary phase materials.

Abstract
The development of efficient techniques for large-scale oligonucleotide purification is of great interest due to the increased demand for antisense oligonucleotides as therapeutics as well as their use for target validation and gene functionalization. This paper describes the use of anion-exchange displacement chromatography for the purification of 20-mer phosphorothioate oligonucleotide from its closely related impurities using low-molecular-mass amaranth as the displacer. Experiments were carried out to examine the effect of the feed load on the performance of the displacement chromatography. In contrast to prior work, displacement chromatography was successfully scaled-up to high column loadings while maintaining high purity and yields. Experiments carried out on a Source 15Q column indicated that crude oligonucleotide loading as high as 39.2 mg/ml of column were readily processed, resulting in product recovery of 86% and purity of 92%. These results demonstrate that anion-exchange displacement chromatography can indeed be employed for large-scale oligonucleotide separations at high column loading.

Abstract
Displacement chromatography of proteins was successfully carried out in both hydrophobic interaction and reversed-phase chromatographic systems using low-molecular weight displacers. The displacers employed for hydrophobic displacement chromatography were water soluble, charged molecules containing several short alkyl and/or aryl groups. Spectroscopy was employed to verify the absence of structural changes to the proteins displaced on these hydrophobic supports. Displacement chromatography on a reversed-phase material was employed to purify a growth factor protein from its closely related variants, demonstrating the high resolutions that can be achieved by hydrophobic displacement chromatography. This process combines the high-resolution/high-throughput characteristics of displacement chromatography with the unique selectivity of these hydrophobic supports and offers the chromatographic engineer a powerful tool for the preparative purification of proteins.

Abstract
The relative efficacy of a variety of low-molecular-mass displacers was examined on three different stationary phase materials. Several homologous series of displacer molecules were evaluated on these ion-exchange resins using a displacer ranking plot based on the steric mass action model. The results demonstrate that while aromaticity and hydrophobicity can play a significant role in the affinity of displacer molecules on polymethacrylate based and hydrophilized polystyrene-divinylbenzene based materials, this effect is much less pronounced on an agarose based resin. The work presented in this paper demonstrates that different structural features of low-molecular-mass displacers can dominate their affinity on various stationary phase materials employed and provides rules of thumb for the design of high affinity, low-molecular-mass displacers for a variety of commercial cation-exchange materials.
