Abstract
Human immunoglobulin M (hIgM) antibodies are considered as hopeful tools for diseases therapy. Therefore, chromatography approaches are used to purify hIgM with a single step. In this study, we prepared a poly(hydroxyethyl methacrylate) based immunoaffinity p(HEMA-I) cryogel column by using cyanamide to immobilize antihuman immunoglobulin on the p(HEMA) cryogel for purification of hIgM in aqueous solution and artificial human plasma. The characterization of the p(HEMA) cryogel column was performed by using a scanning electron microscope (SEM), micro-computerized tomography (µ-CT), Fourier transform infrared spectroscopy (FTIR), swelling degree and macro-porosity. Further, the optimizations of various parameters were performed such as, pH, ionic strength, temperature and concentration of hIgM in aqueous solutions. In addition, the Langmuir adsorption model was supported by experimental results. Maximum adsorbed amount of hIgM corresponded to 11.1 mg/g at pH 5.75 [morpholino ethanesulfonic acid (MES buffer)]. Our results indicated that the p(HEMA-I) cryogel column can be reused at least 10 times without significant loss in adsorption capacity. As a natural source, artificial human plasma was selected for hIgM adsorption and the purity of hIgM was evaluated using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE).

Abstract
This paper deals with the theoretical design and experimental validation of an affinity-based continuous multi-column chromatography process for the purification of single-chain Fragment variable (scFv) antibodies. An open-loop 3-zone pH-gradient simulated moving bed (SMB) process was investigated exploiting the highly specific affinity of metal ions toward histidine-tagged recombinant proteins. The separation problem was simplified by considering the cell culture supernatant as a pseudo-binary mixture. The influence of mobile phase pH on the adsorption isotherm parameters was estimated by the inverse method using recorded pH-gradient batch elution profiles. Suitable operating parameters for the SMB process were identified using an equilibrium stage model and subsequently validated in a lab-scale SMB unit. Finally, the performance of the pH-gradient SMB process was compared against a non-optimized batch process. Biologically active single-chain Fragment variable antibody formats were purified continuously with 9% more recovery, 11 times more productivity (576 mg of purified scFv per day and liter stationary phase in SMB) and enriched by a factor of 2.5 compared to those obtained in the non-optimized batch process.

Abstract
Protease activity from host cell lines may cause product loss or affect the quality of recombinant proteins. In this study, we showed that excipients like glycine and sorbitol reduce the proteolysis of an immunoglobulin M (IgM) in the presence of added proteases like α-chymotrypsin, papain, and pepsin. The activity of the proteases in the IgM-protective environments was conserved or even enhanced as tested using low molecular weight substrates. Thus, a higher resistance against proteolytic degradation appears to be caused by the conformational stabilization of the IgM due to preferential exclusion of sorbitol and glycine.

J Chromatogr A 2013; 1324:171-80.

Abstract
We achieved exceptionally high capacity capture of monoclonal IgG by adding 200 nm starch-coated magnetic particles as nucleation centers, adding polyethylene glycol (PEG), then collecting the particle-associated antibody in a magnetic field. Experimental data suggest that accretion of IgG begins on particle surfaces then continues with fusion of particle-centric accretions up to about 1mm in a process that closely parallels PEG precipitation. An embedded nanoparticle mass of 1.3% of the IgG mass is adequate to enable efficient magnetic collection of the associated IgG. Recovery of purified IgG averaged 98% up to loads of 78 mg of IgG per mg of particles. Converted to an equivalent volume of settled particles, this represents about 58 g IgG per mL of nanoparticles, which is roughly 1000 times higher than the average capacity of commercial protein A porous particles packed in columns. When applied to cell culture harvest clarified by centrifugation and microfiltration, performing the nanoparticle technique under physiological conditions permitted only a 10-fold reduction of host cell protein (HCP) contamination and IgG recovery less than 50%. Application of a more capable clarification method and operating the nanoparticle method at 0.5-1.0M NaCl supported more than 99% HCP reduction and 87% IgG recovery. The high salt concentration also dramatically diminished the influence of operating pH on selectivity. The nanoparticle step was followed by sample application without buffer exchange to a column packed with multimodal electropositive-hydrophobic particles that reduced HCP to 2 ppm. Aggregate content was reduced from 4.9 to 3.6% at the nanoparticle step, then to less than 0.05% at the multimodal step. The multimodal step also removed residual PEG. Overall IgG recovery was 69%. The ability of the system to achieve purity similar to protein A, but dramatically higher productivity than packed columns, suggests that the technique could evolve as a credible option for industrial purification of monoclonal antibodies.

Abstract
We introduce a chromatography method for purification of large proteins and viruses that works by capturing them at a non-reactive hydrophilic surface by their mutual steric exclusion of polyethylene glycol (PEG). No direct chemical interaction between the surface and the target species is required. We refer to the technique as steric exclusion chromatography. Hydroxyl-substituted polymethacrylate monoliths provide a hydrophilic surface and support convective mass transport that is unaffected by the viscosity of the PEG. Elution is achieved by reducing PEG concentration. Selectivity correlates with molecular size, with larger species retained more strongly than smaller species. Retention increases with PEG size and concentration. Salts weaken retention in proportion to their concentration and Hofmeister ranking. Retention is enhanced near the isoelectric point of the target species. Virus binding capacity was measured at 9.9×10(12) plaque forming units per mL of monolith. 99.8% of host cell proteins and 93% of DNA were eliminated. Mass recovery exceeded 90%. IgM capacity was greater than 60 mg/mL. 95% of host cell proteins were eliminated from IgM produced in protein-free media, and mass recovery was up to 90%. Bioactivity was fully conserved by both viruses and antibodies. Process time ranged from less than 30 min to 2 h depending on the product concentration in the feed stream.

Abstract
Mesenchymal stem cells (MSCs) have become one of the most promising cell sources for bone tissue engineering (BTE) applications. In this review, we first highlight recent progress in the understanding of MSC biology, their in vivo niche, multi-faceted contribution to fracture healing and bone re-modelling, and their role in BTE. A literature review from clinicaltrials.gov and Pubmed on clinical usage of MSC for both orthopedic and non-orthopedic indications suggests that translational use of MSC for BTE indications is likely to bear fruit in the ensuing decade. Last, we disscuss the profound influence of ontological and antomical origins of MSC on their proliferation and osteogenesis and demonstrated human fetal MSC (hfMSC) as a superior cellular candidate for off-the-shelf BTE applications. This relates to their superior proliferation capacity, more robust osteogenic potential and lower immunogenecity, as compared to MSC from perinatal and postnatal sources. Furthermore, we discuss our experience in developing a hfMSC based BTE strategy with the integrated use of bioreactor-based dynamic priming within macroporous scaffolds, now ready for evaluation in clinical trials. In conclusion, hfMSC is likely the most promising cell source for allogeneic based BTE application, with proven advantages compared to other MSC based ones.

Abstract
Manufacturing of cell culture-derived virus particles for vaccination and gene therapy is a rapidly growing field in the biopharmaceutical industry. The process involves a number of complex tasks and unit operations ranging from selection of host cells and virus strains for the cultivation in bioreactors to the purification and formulation of the final product. For the majority of cell culture-derived products, efforts focused on maximization of bioreactor yields, whereas design and optimization of downstream processes were often neglected. Owing to this biased focus, downstream procedures today often constitute a bottleneck in various manufacturing processes and account for the majority of the overall production costs. For efficient production methods, particularly in sight of constantly increasing economic pressure within human healthcare systems, highly productive downstream schemes have to be developed. Here, we discuss unit operations and downstream trains to purify virus particles for use as vaccines and vectors for gene therapy.
