Abstract
Peptide affinity chromatography has received increasing attention as an alternative to protein A chromatography in antibody purification. However, its lower selectivity than protein A chromatography has impeded its success in practical applications. In particular, efficient removal of contaminants, including host cell proteins (HCPs) and DNA, is a great challenge for peptide affinity chromatography in monoclonal antibody (mAb) manufacturing. In this work, a biomimetic peptide ligand (bPL), FYWHCLDE, was coupled onto Sepharose 6 Fast Flow (SepFF) to synthesize a peptide affinity gel, SepFF-bPL, for the investigation of the binding mechanism of HCP as well as the feasibility of antibody capture. The results showed that the SepFF-bPL column exhibited effective removal of mAb aggregates as well as mAb capture from feedstocks of various origins, whereas poor removal of HCP and DNA was found. Mechanistic studies of HCP binding indicated that electrostatic interactions dominated HCP binding on the SepFF-bPL gel and that ionic conductivity had a significant influence on HCP binding at low salt concentrations. Thus, combined chromatin extraction and anion exchange adsorption were introduced prior to SepFF-bPL chromatography for initial contaminant removal to reduce mAb aggregation induced by HCP and the loading burden of contaminants in SepFF-bPL chromatography. A proof-of-concept study of the purification train demonstrated a high recovery of mAb (68.7%) and low levels of HCP (23 ppm) and DNA (below the limit of detection) in the final product, which were acceptable for the mandatory requirements in clinical applications. This research provided a deep understanding of HCP binding on the peptide affinity column and led to the development of an effective purification train.

Abstract
Multi-size optimization of ion exchangers based on protein characteristics and understanding of underlying mechanism is crucial to achieve maximum separation performance in terms of adsorption capacity and uptake kinetic. Herein, we characterize the effects of three different sizes, macropore size, protein size, and ligand length, on the protein adsorption capacity and uptake kinetic of macroporous cellulose beads, and provide insights into the underlying mechanism. In detail, (1) for smaller bovine serum albumin, macropore size has a negligible effect on the adsorption capacity, while for larger γ-globulin, larger macropores improve the adsorption capacity due to the high accessibility of binding sites; (2) there is a critical pore size (CPZ), at which the adsorption uptake kinetic is minimum. When pore sizes are higher than the CPZ, uptake kinetics are enhanced by pore diffusion. When pore sizes are lower than CPZ, uptake kinetics are enhanced by surface diffusion; (3) increasing ligand length improves the adsorption capacity by three-dimensionally extended polymer chains in pores and enhances uptake kinetic by improved surface diffusion. This study offers an integrated perspective to qualitatively assess the effects of multiple sizes, providing guidance for designing advanced ion exchangers for protein chromatography.

Abstract
With the growing concerns of polymer-grafted ion-exchange chromatography, the importance of protein adsorption on charged polymer-grafted surfaces cannot be stressed enough. However, a full understanding in adsorption in polymer brushes is still a great challenge due to the lack of in situ characterization technique. In this work, we use quartz crystal microbalance with dissipation to in situ investigate adsorption kinetics of γ-globulin and recombinant human lactoferrin on poly(3-sulfopropyl methacrylate) (pSPM) sensors prepared via atom transfer radical polymerization. With an increase of chain length and grafting density, great increasing amounts of proteins on pSPM-grafted sensors revealed that protein underwent a transition from monolayer to multilayer adsorption. It was attributed to direct protein binding into charged brushes, in which more binding sites involved and more coupled water lost. However, such a strong binding and rigid structure of proteins limited the protein transport in pSPM brushes and "chain delivery" effect. With an increase in grafting density, moreover, denser brushes hindered adjustment in protein conformation in pSPM brushes and further exacerbated protein transport in pSPM brushes. Furthermore, the influence of buffer pH and salt concentration further validated the ion exchange characteristics of protein adsorption into pSPM brushes. The research provided a variety of in situ evidence of protein binding and conformation evolution in pSPM brushes and elucidated mechanism of protein adsorption in pSPM brushes.

Abstract
Here, a m-xylene bisphosphonate immobilized tentacle-type cellulose monolith (BP-PCM) is prepared by atom transfer radical polymerization for lysozyme purification. In the preparation, the m-xylene bisphosphonate was anchored glycidyl methacrylate and then polymerized to enhance the flexibility of the ligands to improve lysozyme adsorption capacity, and glycerol monomethacrylate serves as spacer to further optimize the layers structure and ligands density of the grafted tentacles for satisfactory adsorption capacity. The maximum static and dynamic adsorption capacity (10% breakthrough) of BP-PCM reach to 169.6 and 102.6 mg mL-1, respectively. Moreover, BP-PCM displays weak nonspecific adsorption and is able to successfully enrich lysozyme from diluted chicken egg white, indicating the excellent selectivity. The results demonstrated that BP-PCM is promising for use as high-capacity protein chromatography.

Abstract
The formation of a stable spatial arrangement of protein A ligands is a great challenge for the development of high-capacity polymer-grafted protein A adsorbents due to the complexity in interplay between coupled ligands and polymer chain. In this work, carboxymethyl dextrans (CMDs) with different molecular weight were introduced to provide stable spatial ligand arrangement in CMD-grafted protein A gels to improve IgG adsorption. The result showed that coupling of protein A ligand in CMD-grafted layer had no marked influence on pore size and dextran layers coupled with the ligands were stable in experimental range of salt concentrations. The result of IgG adsorption revealed that carboxymethyl dextran T10, a short CMD, was more suitable as a scaffold for the synthesis of high-capacity protein A gels. Moreover, the maximal adsorption capacity for IgG was obtained to be 96.4 mg/g gel at ionic capacities of 300-350 mmol/L and a ligand density of 15.2 mg/g gel. Dynamic binding capacity for IgG exhibited a higher capacity utilization in CMD-grafted protein A gels than non-grafted protein A gel. The research presented a tactics to establish a stable dextran layer coupled with protein A ligands and demonstrated its importance to improve binding capacity for IgG.

Abstract
The strategy of using polymer-grafted media is effective to create protein chromatography of high capacity and uptake rate, giving rise to an excellent performance in high-throughput protein separation due to its high dynamic binding capacity. Taking the scientific development and technological innovation of protein chromatography as the objective, this review is devoted to an overview of polymer-grafted media reported in the last five years, including their fabrication routes, protein adsorption and chromatography, mechanisms behind the adsorption behaviors, limitations of polymer-grafted media and chromatographic operation strategies. Particular emphasis is placed on the elaboration and discussion on the behaviors of ion-exchange chromatography (IEC) with polymer-grafted media because IEC is the most suitable chromatographic mode for this kind of media. Recent advances in both the theoretical and experimental investigations on polymer-grafted media are discussed by focusing on their implications to the rational design of novel chromatographic media and mobile phase conditions for the development of high-performance protein chromatography. It is concluded that polymer-grafted media are suitable for development of IEC and mixed-mode chromatography with charged and low hydrophobic ligands, but not for hydrophobic interaction chromatography with high hydrophobic ligands and affinity chromatography with ligands that have single binding site on the protein.
