Abstract
Membrane chromatography (MC) is an emerging bioseparation technology combining the principles of membrane filtration and chromatography. In this process, one type of molecule is adsorbed in the stationary phase, whereas the other type of molecule is passed through the membrane pores without affecting the adsorbed molecule. In subsequent the step, the adsorbed molecule is recovered by an elution buffer with a unique ionic strength and pH. Functionalized microfiltration membranes are usually used in radial flow, axial flow, and lateral flow membrane modules in MC systems. In the MC process, the transport of a solute to a stationary phase is mainly achieved through convection and minimum pore diffusion. Therefore, mass transfer resistance and pressure drop become insignificant. Other characteristics of MC systems are a minimum clogging tendency in the stationary phase, the capability of operating with a high mobile phase flow rate, and the disposable (short term) application of stationary phase. The development and application of MC systems for the fractionation of individual proteins from whey for investigation and industrial-scale production are promising. A significant income from individual whey proteins together with the marketing of dairy foods may provide a new commercial outlook in dairy industry. In this review, information about the development of a MC system and its applications for the fractionation of individual protein from whey are presented in comprehensive manner.

Abstract
Macroporous cellulose and glass membranes were prepared from filter paper and glass fiber filter, respectively. To enhance their stability, the cellulose membranes were crosslinked with epichlorohydrin, and the glass membranes were crosslinked with glutaraldehyde or organic bifunctional silanes. Several pathways for the modification, activation, and ligand immobilization were used and compared. For cellulose membranes, the diazotization method provided the best results, whereas the glutaraldehyde method provided the best performance for glass membranes, regarding both their stability and ligand immobilization capacity. The characterization of the membranes was made by using a triazine dye, bovine serum albumin, and trypsin as test ligands. The membrane morphologies and the uniformities of ligand distribution across the membrane cartridges were investigated. Numerous affinity ligands were immobilized onto the membranes, and the prepared affinity membranes have been used to separate or purify concanavalin A, peroxidase, protease inhibitors, globulin, fibronectin, and other biomolecules.

Abstract
Downstream purification processes for monoclonal antibody production typically involve multiple steps; some of them are conventionally performed by bead-based column chromatography. Affinity chromatography with Protein A is the most selective method for protein purification and is conventionally used for the initial capturing step to facilitate rapid volume reduction as well as separation of the antibody. However, conventional affinity chromatography has some limitations that are inherent with the method, it exhibits slow intraparticle diffusion and high pressure drop within the column. Membrane-based separation processes can be used in order to overcome these mass transfer limitations. The ligand is immobilized in the membrane pores and the convective flow brings the solute molecules very close to the ligand and hence minimizes the diffusional limitations associated with the beads. Nonetheless, the adoption of this technology has been slow because membrane chromatography has been limited by a lower binding capacity than that of conventional columns, even though the high flux advantages provided by membrane adsorbers would lead to higher productivity. This review considers the use of membrane adsorbers as an alternative technology for capture and polishing steps for the purification of monoclonal antibodies. Promising industrial applications as well as new trends in research will be addressed.

Abstract
A mathematical model for the adsorption of biomolecules on affinity membranes is presented. The model considers convection, diffusion and adsorption kinetics on the membrane module as well as the influence of dead end volumes and lag times; an analysis of flow distribution on the whole system is also included. The parameters used in the simulations were obtained from equilibrium and dynamic experimental data measured for the adsorption of human IgG on A2P-Sartoepoxy affinity membranes. The identification of a bi-Langmuir kinetic mechanisms for the experimental system investigated was paramount for a correct process description and the simulated breakthrough curves were in good agreement with the experimental data. The proposed model provides a new insight into the phenomena involved in the adsorption on affinity membranes and it is a valuable tool to assess the use of membrane adsorbers in large scale processes.

Abstract
Breakthrough performance of linear-DNA adsorption on ion-exchange membrane columns was theoretically and experimentally investigated using batch and fixed-bed systems. System dispersion curves showed the absence of flow non-idealities in the experimental arrangement. Breakthrough curves were not significantly affected by flow-rate or inlet solution concentration. In the theoretical analysis a model was integrated by the serial coupling of the membrane transport model and the system dispersion model. A transport model that considers finite kinetic rate and column dispersed flow was used in the study. A simplex optimization routine coupled to the solution of the partial differential model equations was employed to estimate the maximum adsorption capacity constant, the equilibrium desorption constant and the forward interaction rate-constant, which are the parameters of the membrane transport model. Through this approach a good prediction of the adsorption phenomena is obtained for inlet concentrations and flow rates greater than 0.2 mg/ml and 0.16 ml/min.

Abstract
Increasing reports regarding the isolation or purification of biospecies for therapeutic purpose using the immobilized metal affinity chromatography have been presented in recent years. At the same time, membrane chromatography technique has also gained more and more attention for their advantage in speeding the separation process. The immobilized metal affinity membrane technique developed by combining these two techniques may provide an alternative potential tool for separating the therapeutically relevant biospecies. In this review paper, the features of the immobilized metal affinity membranes are discussed and concentrated on three subtopics: membrane matrices, immobilized metal affinity method, and membrane module designs. Several examples of practically applying the immobilized metal affinity membranes on the purification of potential therapeutics reported in the literature are subsequently presented. Lastly, this review also provides an overall evaluation on the possible advantages and problems existing in this technique to point out opportunities and further improvements for more applied development of the immobilized metal affinity membranes.

Abstract
Frontal affinity chromatography (FAC) is a simple but powerful method to analyze molecular interactions between an analyte and an immobilized ligand by calculating the extent of retardation of the elution front. By combination of FAC with a PE-Mariner electrospray ionization mass spectrometry, a very efficient and straightforward procedure was developed herein for analyzing the binding properties of different inhibitors of the epidermal growth factor receptor (EGFR). In this study, a polyclonal antibody prepared with a known anti-EGFR inhibitor coupled with bovine serum albumin was adopted as the stationary phase in the FAC system. Using the antibody to mimic the receptor, other different anti-EGFR inhibitors as well as the small-molecule half-antigen itself were recognized directly from the crude extract of herb, which afforded us a novel promising approach for the efficient screening of lead compounds or drug candidates from natural resources.

Abstract
The scaleup and optimization of large-scale affinity-chromatographic operations in the recovery, separation and purification of biochemical components is of major industrial importance. The development of mathematical models to describe affinity-chromatographic processes, and the use of these models in computer programs to predict column performance is an engineering approach that can help to attain these bioprocess engineering tasks successfully. Most affinity-chromatographic separations are operated in the frontal mode, using fixed-bed columns. Purely diffusive and perfusion particles and membrane-based affinity chromatography are among the main commercially available technologies for these separations. For a particular application, a basic understanding of the main similarities and differences between particle and membrane frontal affinity chromatography and how these characteristics are reflected in the transport models is of fundamental relevance. This review presents the basic theoretical considerations used in the development of particle and membrane affinity chromatography models that can be applied in the design and operation of large-scale affinity separations in fixed-bed columns. A transport model for column affinity chromatography that considers column dispersion, particle internal convection, external film resistance, finite kinetic rate, plus macropore and micropore resistances is analyzed as a framework for exploring further the mathematical analysis. Such models provide a general realistic description of almost all practical systems. Specific mathematical models that take into account geometric considerations and transport effects have been developed for both particle and membrane affinity chromatography systems. Some of the most common simplified models, based on linear driving-force (LDF) and equilibrium assumptions, are emphasized. Analytical solutions of the corresponding simplified dimensionless affinity models are presented. Particular methods for estimating the parameters that characterize the mass-transfer and adsorption mechanisms in affinity systems are described.

Abstract
Affinity chromatography is unique among separation methods as it is the only technique that permits the purification of proteins based on biological functions rather than individual physical or chemical properties. The high specificity of affinity chromatography is due to the strong interaction between the ligand and the proteins of interest. Membrane separation allows the processing of a large amount of sample in a relatively short time owing to its structure, which provides a system with rapid reaction kinetics. The integration of membrane and affinity chromatography provides a number of advantages over traditional affinity chromatography with porous-bead packed columns, especially with regard to time and recovery of activity. This review gives detailed descriptions of materials used as membrane substrates, preparation of basic membranes, coupling of affinity ligands to membrane supports, and categories of affinity membrane cartridges. It also summarizes the applications of cellulose/glycidyl methacrylate composite membranes for proteins separation developed in our laboratory.

Abstract
An affinity membrane grafted with protein A/G or protein A was characterized for human and mouse immunoglobulins G purification. Breakthrough curves up to ligand saturation were measured and used to study the effects of flow velocities, feed solution concentrations and protein A/G versus protein A membranes. Increased flow-rate did not decrease the amount of IgG bound to the membranes. Increased feed solution concentration allowed more IgG to bind prior to breakthrough. Kinetic parameters for immunoglobulins G sorption to immobilized protein A were measured in batch experiments. The static binding capacity was determined to be 6.6 mg ml(-1) membrane volume. Finally, this affinity membrane was used to purify IgG from cell culture supernatant. The electrophoresis of the purified IgG fractions did not show any contaminant.

Abstract
Sorption of bovine serum albumin to commercial 150-micron pore size membranes was measured in batch and flow experiments. For residence times of 2-40 min, early and broad breakthrough curves and broad asymmetric elution peaks were observed that depended strongly on flow-rate. System dispersion could not explain the flow-rate dependence. Breakthrough and elution curves were analyzed using new models that included Langmuir sorption, convection and diffusion. From the analysis, film mass transfer resistance was found to be the rate-limiting factor. The maximum allowable pore size that eliminates this limitation was calculated for different molecular weight solutes.
