Abstract
PEGylated protein purification with the required quality attributes has represented a bioengineering challenge and Affinity Monolith Chromatography (AMC) has never been exploited for this goal. This work reports the generation of a heparin-modified affinity monolith disk by reductive alkylation with raised ligand density for its use as chromatographic support in the separation of lysozyme PEGylation reactions (LPRs) with three different PEG sizes (1, 20 and 40 kDa). For immobilized heparin determination a modified toluidine colorimetric assay adapted to microplate format was proposed. The heparin modified-disk was able to differentiate positional isomers of 20 kDa mono-PEGylated lysozyme at neutral pH using a salt linear gradient. Identity of PEG-conjugates was verified by SDS-PAGE and positional isomers were partially characterized by peptide mapping mass spectrometry. 20 kDa mono-PEGylated lysozyme conjugate purity (99.69 ± 0.05%) was comparable with traditional chromatographic methods while productivity (0.0964 ± 0.0001 mg/mL*min) was increased up to 6.1 times compared to that obtained in heparin packed-bed affinity chromatography procedures. The proposed AMC method represents a reliable, efficient, easy-handling, fast and single-step operation for the analysis or preparative isolation of PEGylated proteins containing a heparin binding domain.

Development and Characterization of PEGylated Chromatographic Monoliths as a Novel Platform for the Separation of PEGylated RNase a Isomers. ADVANCES IN POLYMER TECHNOLOGY 2019.

Abstract
PEGylated or polyethylene glycol-modified proteins have been used as therapeutic agents in different diseases. However, the major drawback in their procurement is the purification process to separate unreacted proteins and the PEGylated species. Several efforts have been done to separate PEGylation reactions by chromatography using different stationary phases and modified supports. In this context, this study presents the use of chromatographic monoliths modified with polyethylene glycol (PEG) to separate PEGylated Ribonuclease A (RNase A). To do this, Convective Interaction Media (CIM) Ethylenediamine (EDA) monolithic disks were PEGylated using three PEG molecular weights (1, 10, and 20 kDa). The PEGylated monoliths were used to separate PEGylated RNase A modified, as well, with three PEG molecular weights (5, 20, and 40 kDa) by hydrophobic interaction chromatography. Performance results showed that Bovine Serum Albumin (BSA) can bind to PEGylated monoliths and the amount of bound BSA increases when ammonium sulfate concentration and flow rate increase. Furthermore, when PEGylated RNase A was loaded into the PEGylated monoliths, PEG-PEG interactions predominated in the separation of the different PEGylated species (i.e., mono and di-PEGylated). It was also observed that the molecular weight of grafted PEG chains to the monolith impacts strongly in the operation resolution. Interestingly, it was possible to separate, for the first time, isomers of 40 kDa PEGylated RNase A by hydrophobic interaction chromatography. This technology, based on PEGylated monoliths, represents a new methodology to efficiently separate proteins and PEGylated proteins. Besides, it could be used to separate other PEGylated molecules of biopharmaceutical or biotechnological interest.

Abstract
N-terminus-specific PEGylation was used to produce mono-PEGylated lysozyme. However, some di- and tri-PEGylated proteins were also produced due to side chain reaction. The reaction products were characterized by chromatographic and electrophoretic methods. Commercial cation exchange membrane Sartobind S was used for chromatographic purification of PEGylated lysozyme, the basis of separation being the shielding of protein charge by PEG. Using the membrane chromatographic method, lysozyme and mono-, di-, and tri-PEGylated lysozyme could be resolved into separate peaks. Increasing the superficial velocity during chromatographic separation from 24 cm/h to 240 cm/h increased both protein binding capacity and resolution due to enhancement of protein mass transfer coefficient.

Abstract
Monolithic columns were introduced in the early 1990s and have become increasingly popular as efficient stationary phases for most of the important chromatographic separation modes. Monoliths are functionally distinct from porous particle-based media in their reliance on convective mass transport. This makes resolution and capacity independent of flow rate. Monoliths also lack a void volume. This eliminates eddy dispersion and permits high-resolution separations with extremely short flow paths. The analytical value of these features is the subject of recent reviews. Nowadays, among other types of rigid macroporous monoliths, the polymethacrylate-based materials are the largest and most examined class of these sorbents. In this review, the applications of polymethacrylate-based monolithic columns are summarized for the separation, purification and analysis of low and high molecular mass compounds in the different HPLC formats, including micro- and large-scale HPLC modes.

Abstract
A method for the fast separation of proteins and identification of their modifications based on the use of monolithic chromatographic media and mass spectrometric techniques is described. This method has been developed and applied to the analysis of malt proteins and its posttranslational modifications (glycation). Glycation, one of the most common forms of posttranslational modifications (PTM), can be detected in both biological and industrial samples. Our attention was focused on the investigations of possible chemical modifications of water-soluble barley proteins during malting process by combination of anion-exchange chromatography with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The malt extract was directly fractioned by anion-exchange chromatography using short monolithic columns and a linear gradient from 0 to 700 mM NaCl. Sufficient fractionation was obtained for malt sample, which demonstrates the potential of anion-exchange chromatography on this type of column. Proteins in separated fractions were identified by MALDI-TOF/TOF MS. Our proteomic analysis provided the identification of the major proteins present in the malt that were found to be heterogeneously glycated after malting. One of these proteins: nonspecific lipid transfer protein 1 (LTP1) can be used as a marker for characterization of glycation during malting. This protein and its modifications can be easily determined by the developed method.

Abstract
Modern downstream processing requires fast and highly effective methods to obtain large quantities of highly pure substances. Commonly applied method for this purpose is chromatography. However, its main drawback is its throughput since purification, especially of large molecules, requires long process time. To overcome this problem several new stationary phases were introduced, among which short layer monoliths show superior properties for many applications. The purpose of this review is to give an overview about short methacrylate monolithic columns commercialised under the trademark Convective Interaction Media (CIM). Their unique properties are described from different perspectives, explaining reasons for their application on various areas. Approaches to prepare large volume methacrylate monolithic column are discussed and optimal solutions are given. Different examples of CIM monolithic column implementation are summarised in the last part of the article to give the reader an idea about their advantages.
