Abstract
Affinity monolith chromatography (AMC) is a liquid chromatographic technique that utilizes a monolithic support with a biological ligand or related binding agent to isolate, enrich, or detect a target analyte in a complex matrix. The target-specific interaction exhibited by the binding agents makes AMC attractive for the separation or detection of a wide range of compounds. This article will review the basic principles of AMC and recent developments in this field. The supports used in AMC will be discussed, including organic, inorganic, hybrid, carbohydrate, and cryogel monoliths. Schemes for attaching binding agents to these monoliths will be examined as well, such as covalent immobilization, biospecific adsorption, entrapment, molecular imprinting, and coordination methods. An overview will then be given of binding agents that have recently been used in AMC, along with their applications. These applications will include bioaffinity chromatography, immunoaffinity chromatography, immobilized metal-ion affinity chromatography, and dye-ligand or biomimetic affinity chromatography. The use of AMC in chiral separations and biointeraction studies will also be discussed.

Abstract
Epidemiological studies have shown that regular consumption of food based on whole-grain cereals and their products is associated with reduced risks of various types of degenerative chronic diseases. Food proteins are considered an important source of nutraceutical peptides and amino acids that can exert biological functions to promote health and prevent disease, including cancer. There have been several reports on peptides with anti-tumour activity in recent years. Plant-derived peptides, such as rapeseed, amaranth and soybean lunasin have received main attention. In this review, we extend this vision to analyse the evidence of current advances in peptides in cereals such as wheat, maize, rice, barley, rye and pseudocereals compared with soybean. We also show evidence of several mechanisms through which bioactive peptide exerts anti-tumour activity. Finally, we report the current status of major strategies for the fractionation, isolation and characterisation of bioactive peptides in cereals. BIOLOGICAL SIGNIFICANCE In recent reports, it has been shown that peptides are an interesting alternative in the search for new treatments for cancer. One of the most studied sources of these peptides is food proteins; however, a review that includes more recent findings for cereals as a potential source of bioactive peptides in the treatment of cancer, the techniques for their isolation and characterisation and the assays used to prove their bioactivity is not available. This review can be used as a tool in the search for new sources of anti-cancer peptides. The authors have no conflicts of interest, financial or otherwise.

Abstract
An in-line SPE method coupled to CE was developed for the analysis of DNA. The amino silica monolith was prepared in situ by polymerization of tetraethoxysilane and N-(β-aminoethyl)-γ-aminopropyltriethoxysilane in ethanol aqueous solution at the inlet end of a 100 μm id fused-silica capillary, and the remaining part of the capillary was used as separation channel. The procedure for this in-line SPE-CE method was constructed on the basis of investigation on operational conditions such as the introduction mode of sieving matrix, the composition of elution solvent and the elution time. Twenty millimolar ammonium hydroxide was demonstrated to be effective for DNA desorption from the monolith, and linear poly(N-isopropylacrylamide) was used as the separation matrix. The proposed method could achieve limits of detection of 0.065-0.123 ng/mL for six DNA fragments ranging 100-2000 bp. Compared with conventional CE, preconcentration factors of over 100 times were obtained. The applicability of the in-line SPE-CE method was further demonstrated by analyzing plasmid DNA from Escherichia coli crude lysate.

Abstract
The post-translational modification (PTM) of proteins is a common biological mechanism for regulating protein localization, function, and turnover. The direct analysis of modifications is required because they are not coded by genes, and thus are not predictable. Different MS-based proteomic strategies are used for the analysis of PTMs, such as phosphorylation and glycosylation, and are composed of a structural simplification step of the protein followed by specific isolation step to extract the classes of modified peptides (also called "sub-proteomes") before mass spectrometry. This specific isolation step is necessary because PTMs occur at a sub-stoichiometric level and signal suppression of the modified fractions in the mass spectrometer occurs in the presence of the more-abundant non-modified counterpart. The request of innovative analytical strategies in PTM studies is the capability to localize the modification sites, give detailed structural information on the modification, and determine the isoform composition with increased selectivity, sensitivity, and throughput. This review focuses on the description of recent integrated analytical systems proposed for the analysis of PTMs in proteins, and their application to profile the glycoproteome and the phosphoproteome in biological samples. Comments on the difficulties and usefulness of the analytical strategies are given.

Abstract
The article brings a comprehensive survey of recent developments and applications of high-performance capillary electromigration methods, zone electrophoresis, ITP, IEF, affinity electrophoresis, EKC, and electrochromatography, to analysis, preparation, and physicochemical characterization of peptides. New approaches to the theoretical description and experimental verification of electromigration behavior of peptides and to methodology of their separations, such as sample preparation, adsorption suppression, and detection, are presented. Novel developments in individual CE and CEC modes are shown and several types of their applications to peptide analysis are presented: conventional qualitative and quantitative analysis, purity control, determination in biomatrices, monitoring of chemical and enzymatical reactions and physical changes, amino acid and sequence analysis, and peptide mapping of proteins. Some examples of micropreparative peptide separations are given and capabilities of CE and CEC techniques to provide important physicochemical characteristics of peptides are demonstrated.

Abstract
A hydroxylated poly(glycidyl methacrylate-co-ethylene dimethacrylate) (GMA-co-EDMA) monolithic capillary was prepared and investigated for in-tube solid-phase microextraction (SPME). The polymer monolith was synthesized by in-situ polymerization of GMA and EDMA in the presence of dodecanol and toluene as the mixed porogenic solvents. After polymerization, glycidyl groups were hydrolyzed with sulfuric acid to produce diol groups at the surface of the porous monolith. To investigate the extraction mechanism, several groups of model analytes (including neutral, acidic and basic) were selected to perform extractions. The resulting monolith showed high extraction selectivity towards polar compounds, which resulted from the enhancement of dipole-dipole and hydrogen bonding interactions relative to hydrophobic interactions. The equilibrium extraction time profiles were also monitored for those model compounds to assess the extraction capacity of the monolithic capillary. Moreover, the hydroxylated poly(GMA-co-EDMA) monolithic capillary exhibited satisfactory reproducibility and stability. Finally, the in-tube SPME-HPLC method, based on the developed monolithic capillary as the extraction media, was successfully applied to the determination of five polar organic contaminants in lake water.

Abstract
Proteomics is defined as the analysis of part or all of the protein components of a complex biological system (a cell, organ or tissue) at a given moment. Due to the huge number of proteins encoded by the genome, novel analytical techniques must be developed to meet the need of large scale analysis. This has led to the hyphenation of multiple techniques to achieve this object. Here current status of the hyphenated analytical techniques of one-dimensional and multidimensional liquid chromatography-mass spectrometry for shotgun proteomic analysis is reviewed, and on-line techniques for automated sample preparation and injection are also covered. In addition, the hyphenated techniques for peptidome analysis are also covered.

Abstract
This review summarizes the development of monolithic materials, including both organic and inorganic polymers, according mainly to the papers published in the past two years. Due to their good permeability, fast mass transfer, high stability, and their ease of modification, such materials have been widely used in microcolumn separation systems, not only as stationary phases for CEC and capillary HPLC, but also as substances for sample concentration and enzyme reactor. All the research results demonstrate that monolithic materials in microseparation systems can be expected to play an increasingly important role in the analysis of complex samples.

Abstract
Immobilized metal affinity chromatography (IMAC) is a commonly used technique for phosphoproteome analysis due to its high affinity for adsorption of phosphopeptides. Miniaturization of IMAC column is essential for the analysis of a small amount of sample. Nanoscale IMAC column was prepared by chemical modification of silica monolith with iminodiacetic acid (IDA) followed by the immobilization of Fe3+ ion inside the capillary. It was demonstrated that Fe3+-IDA silica monolithic IMAC capillary column could specifically capture the phosphopeptides from tryptic digest of alpha-casein with analysis by MALDI-TOF MS. The silica monolithic IMAC capillary column was manually coupled with nanoflow RPLC/nanospray ESI mass spectrometer (muRPLC-nanoESI MS) for phosphoproteome analysis. The system was validated by analysis of standard phosphoproteins and then it was applied to the analysis of protein phosphorylation in mouse liver lysate. Besides MS/MS spectra, MS/MS/MS spectra were also collected for neutral loss peak. After database search and manual validation with conservative criteria, 29 singly phosphorylated peptides were identified by analyzing a tryptic digest of only 12 mug mouse liver lysate. The results demonstrated that the silica monolithic IMAC capillary column coupled with muRPLC-nanoESI MS was very suitable for the phosphoproteome analysis of minute sample.

Magnetic poly(ethylene glycol dimethacrylate-N-methacryloyl-(L)-histidine methyl ester) [mag-poly(EGDMA-MAH) beads, 50-100 microm in diameter, were produced by suspension polymerization for affinity depletion of immunoglobulin G (IgG) from human serum. Cu2+ ions were complexed directly via MAH groups (Cu2+ loading: 4.1 micromol/g). IgG depletion studies were performed by magnetically stabilized fluidized bed column. Acetate, Tris-HCl, MES and phosphate buffers all allow adsorption of similar quantities of IgG (27.3-45.6 mg/g). MOPS and HEPES allow higher adsorption quantities (79.6 mg/g and 74.1mg/g, respectively). Maximum adsorption capacities in MOPS buffer were 46.8 mg/g for mag-poly(EGDMA-MAH) and 102.1mg/g for Cu2+ chelated mag-poly(EGDMA-MAH) beads. The adsorption capacity decreased drastically from 102.1mg/g to 30.7 mg/g with the increase of the flow rate from 0.2 ml/min to 3.5 ml/min. The elution studies were performed by 1.0M NaCl. The elution results demonstrated that the adsorption of IgG to the adsorbent was reversible. To test the efficiency of IgG depletion from human serum, proteins in the serum and eluted portion were analyzed by two-dimensional gel electrophoresis. The depletion efficiency for IgG was above 99.4%. Eluted proteins include mainly IgG, and a small number of non-albumin proteins such as apo-lipoprotein A1, sero-transferrin, haptoglobulin and alpha1-antitrypsin. When anti-HSA-sepharose adsorbent is used together with our metal-chelated mag-beads, IgG and HSA can be depleted in a single step.

Abstract
The importance of monolithic (continuous) beds is connected with their easy preparation and the far-reaching possibilities of modification of their surface and porous properties. These properties make them particularly attractive for the analysis of biologically important compounds characterized by a wide spectrum of physicochemical properties. This review summarizes their preparation methods as well as their application as continuous beds for determination of such biologically important compounds as catecholamines, vitamins, flavonoids, amino acids, peptides, and proteins.

Abstract
A capillary-assembled microchip (CAs-CHIP), prepared by simply embedding square capillaries in a lattice polydimethylsiloxane (PDMS) channel plate with the same channel dimensions as the outer dimensions of the square capillaries, has been used as a diffusion-based pretreatment attachment in capillary electrophoresis (CE). Because the CAs-CHIPs employ square-section channels, diffusion-based separation of small molecules from sample solutions containing proteins is possible by using the multilayer flow formed in the square section channel. When a solution containing high-molecular-weight and low-molecular-weight species makes contact with a buffer solution, the low-molecular-weight species, which have larger diffusion coefficients than the high-molecular-weight species, can be collected in a buffer-solution phase. The collected solution containing the low-molecular-weight species is introduced into the separation capillary to be analyzed by CE. This type of system can be used for CE analysis in which pretreatment is required to remove proteins. In this work a fluorescently labeled protein and rhodamine-based molecules were chosen as model species and a feasibility study was performed. ![]()

Abstract
Compared to chromatography-based techniques, the concentration limits of detection (CLOD) associated with capillary electrophoresis are worse, and these have largely precluded their use in many practical applications. To overcome this limitation, researchers from various disciplines have exerted tremendous efforts toward developing strategies for increasing the concentration sensitivities of capillary electrophoresis (CE) systems, via the so-called sample enrichment techniques. This review highlights selected developments and advances in this area as applied to the analyses of proteins and peptides in the last 5 years.

Abstract
Monoliths are attractive stationary phases for purification of large biomolecules like proteins because of their flow-unaffected properties. Isolation of histidine containing proteins to high purity can be efficiently performed using metal-chelate interactions within a single chromatographic step. In this work, we investigated properties of commercial metal-chelate methacrylate monoliths-Convective Interaction Media (CIM). Analytical CIM disk monolithic columns and CIM 8 ml monolithic columns were used for purification of tumor necrosis factor-alpha (TNF-alpha) analog LK-801 and green fluorescence protein with 6 histidine tag (GFP-6His). In both cases, purity over 90% was achieved. Dynamic binding capacity at 10% of breakthrough was around 17-18 mg/ml for LK-801 and around 30 mg/ml for GFP-6His. Adsorption isotherm revealed that the maximal capacity is achieved at protein concentration above 60 microg/ml. Dynamic binding capacity and resolution were found to be flow unaffected.

Abstract
A nanoliter trypsin-based monolithic microreactor coupled with muRPLC-MS/MS was reported for shotgun proteome analysis. The proteins were rapidly digested by the microreactor, and the resulting protein digests were directly loaded onto a muRPLC column for separation followed with detection of the eluted peptides by tandem mass spectrometer. The digestion efficiency and stability of the microreactor was demonstrated by using bovine serum albumin as a model protein. When compared with an incubation time of more than 10 h by free trypsin in the conventional digestion approach, protein mixtures can be digested by the microreactor in several minutes. This system was applied to the analysis of the total cell lysate of Saccharomyces cerevisiae. After a Sequest database search, a total of 1578 unique peptides corresponding to 541 proteins were identified when 590 ng yeast protein was digested by the microreactor with an incubation time of only 1 min.
