Abstract
Antibodies are provided in a variety of formats that include antiserum, hybridoma culture supernatant, or ascites. They can all be used successfully in crude form for the detection of target antigens by immunoassay. However, it is advantageous to use purified antibody in defined quantity to facilitate assay reproducibility, economy, and reduced interference of nonspecific components as well as improved storage, stability, and bio-conjugation. Although not always necessary, the relative simplicity of antibody purification using commercially available protein-A, protein-G, or protein-L resins with basic chromatographic principles warrants purification when antibody source material is available in sufficient quantity. Here, we define three simple methods using immobilized (1) protein-A, (2) protein-G, and (3) protein-L agarose beads to yield highly purified antibody.

Abstract
We have developed a fusion protein (CBD-LG) incorporating a cellulose-binding domain and an antibody binding domain, protein LG, to provide an adaptor molecule for cell separation with regenerated cellulose hollow fiber arrays. A single hollow fiber cell adhesion assay utilizing a CD34+ cell line, KG1a, was used to investigate whether ligand affinity interactions were strong enough for cell attachment and separation. CBD-LG efficiently captured CD34+ cells labeled with the mouse IgG2a monoclonal antibody MHCD3400. However, it was not possible to bind CD34+ cells labeled with an IgG1 antibody (HPCA-2). The low affinity of HPCA-2 for LG was overcome by secondary antibodies: KG1a cells that were dual labeled with HPCA-2 followed by rat anti-mouse IgG1 adhered inside hollow fibers coated with CBD-LG. Alternatively, immobilized rabbit polyclonal anti-mouse IgG1 captured cells labeled with HPCA-2. The development of an adaptor molecule to display recombinant domains at the surface of hollow fibers will be an effective tool to investigate cellular ligand-receptor interactions, a necessary step in the development of hollow fiber bioreactors for manufacture of human cellular products.

Abstract
Antibody purification seems to be safely ensconced in a platform, now well-established by way of multiple commercialized antibody processes. However, natural evolution compels us to peer into the future. This is driven not only by a large, projected increase in the number of antibody therapies, but also by dramatic improvements in upstream productivity, and process economics. Although disruptive technologies have yet escaped downstream processes, evolution of the so-called platform is already evident in antibody processes in late-stage development. Here we perform a wide survey of technologies that are competing to be part of that platform, and provide our [inherently dangerous] assessment of those that have the most promise.

Abstract
This work investigated the adsorption of autoantibodies such as anti-SS-A/Ro, anti-SS-B/La, anti-Sm, and anti-dsDNA on protein L-agarose gel. In order to determine better conditions for IgG adsorption on this matrix, some buffer systems were tested. Adsorption data were analyzed using the Langmuir and Langmuir-Freundlich isotherm models. The experimental isotherms were best described by the Langmuir-Freundlich model, which indicated negative and positive cooperativities for binding in the presence of PBS and HEPES buffers, respectively. The K(d) values for phosphate buffered saline solution (PBS) and hydroxyethylpiperazine ethanesulfonic acid (HEPES) were 2.8 x 10(-7) M and 3.2 x 10(-7) M, respectively, which indicate a high affinity between IgG and the immobilized protein L. The amount of protein adsorbed per amount of protein loaded was high for anti-Sm (44%) and anti-dsDNA (46%), but low for anti-SS-B/La (9%). The amount of albumin adsorbed was lower than 0.06 mg/mL, which may remove the need for a plasma replacement solution in clinical apheresis.

Abstract
The development and characterization of an artificial protein L (PpL) for the affinity purification of antibodies is described. Ligand 8/7, which emerged as the lead from a de novo designed combinatorial library of ligands, inhibits the interaction of PpL with IgG and Fab by competitive ELISA and shows negligible binding to Fc. The ligand 8/7 adsorbent (Ka approximately 10(4) M(-1)) compared well with PpL in binding to immunoglobulins from different classes and sources and, in addition, bound to IgG1 with K and lambda isotypes (92% and 100% of loaded protein) and polyclonal IgG from sheep, cow, goat and chicken. These properties were also reflected in the efficient isolation of immunoglobulins from crude samples.

Abstract
Rational design and combinatorial chemistry were utilized to search for lead protein L (PpL) mimetics for application as affinity ligands for the purification of antibodies and small fragments, such as Fab and scFv, and as potential diagnostic or therapeutic agents. Inspection of the key structural features of the complex between PpL and human Fab prompted the de novo design and combinatorial synthesis of a 169-membered solid-phase ligand library, which was assessed for binding to human IgG and subsequent selectivity for the Fab fragment. Eight ligands were selected, chemically characterized and compared with a commercial PpL-adsorbent for binding pure immunoglobulin fractions. The most promising lead, ligand 8/7, when immobilized on an agarose support, behaved in a similar fashion to PpL in isolating Fab fragments from papain digests of human IgG to a final purity of 97%.

Abstract
The professional antigen presenting cell (APC) plays an essential role in the initiation and propagation of the acquired immune response. Thus, much work has been done in designing strategies that target vaccine antigen (Ag) to APC. Utilizing recombinant DNA technology, we have created a unique two-component system that delivers biotinylated Ag to the Fc gamma receptor type I (FcgammaRI) on APC. Our studies demonstrate that we can successfully engineer FcgammaRI-specific targeting element proteins that simultaneously bind both biotin and recognize FcgammaRI. Additionally, we are able to engineer biotinylated Ag, which form functional elements when adsorbed onto latex microspheres. Furthermore, the targeting and functional element components bind to each other and successfully form two-component immunogens. T-cell activation in response to targeted Ag-laden microspheres is 10- to 100-fold greater than the response to the non-targeted Ag-laden microspheres. This enhancement is 100- to 1000-fold greater than the responses generated to soluble Ag. Thus, our results suggest that specific targeting of Ag-laden microspheres to FcgammaRI may significantly enhance the adjuvant properties of microparticulate delivery systems. Further development of this system may help to elucidate the mechanisms involved in generating enhanced responses to APC-targeted vaccines and significantly advance vaccine technology.

Abstract
A novel biochromatographic principle is introduced taking the quantitative analysis of affinity interactions between antibodies and immobilized group specific ligands (protein A, G, and L) as example. The name high performance monolith affinity chromatography (HPMAC) is proposed for this technique. HPMAC uses rigid, macroporous monoliths, so-called convective interaction media (CIM)-disks, as stationary phase. An optimized procedure is described for the covalent immobilization of the group specific affinity ligands to such disks. The binding of polyclonal bovine IgG and a recombinant human antibody (type IgGl-kappa) to all affinity disks is discussed. An essential feature of HPMAC is its compatibility to unusually high mobile phase flow rates ( > 4 ml/min). Chromatographic experiments are thus completed within seconds without significant loss in binding capacity and retentive power. This makes HPMAC a promising tool for applications in fast process monitoring or screening. As an example for the former, the direct quantitative isolation of recombinant antibodies from serum-free culture supernatant is demonstrated.
