Abstract
The capacity of many proteins to interact with natural or synthetic polyanions has been exploited for modulating their biological action. However, the polydispersity of these macromolecular polyanions as well as their poor specificity is a severe limitation to their use as drugs. An emerging trend in this field is the synthesis of homogeneous and well-defined polyanion-peptide conjugates, which act as bivalent ligands, with the peptide part bringing the selectivity of the scaffold. Alternately, this strategy can be used for improving the binding of short peptides to polyanion-binding protein targets. This work describes the design and first synthesis of homogeneous polysulfonate-peptide conjugates using thiocarbamate ligation for binding to the extracellular domain of MET tyrosine kinase receptor for hepatocyte growth factor.

Abstract
In the last decade, carbohydrate microarrays have been core technologies for analyzing carbohydrate-mediated recognition events in a high-throughput fashion. A number of methods have been exploited for immobilizing glycans on the solid surface in a microarray format. This microarray-based technology has been widely employed for rapid analysis of the glycan binding properties of lectins and antibodies, the quantitative measurements of glycan-protein interactions, detection of cells and pathogens, identification of disease-related anti-glycan antibodies for diagnosis, and fast assessment of substrate specificities of glycosyltransferases. This review covers the construction of carbohydrate microarrays, detection methods of carbohydrate microarrays and their applications in biological and biomedical research.

Abstract
The interaction of polysaccharides with proteins modulates or triggers many biological effects. In particular, heparan sulphate proteoglycans (HSPGs) have multiple regulatory interactions with growth factors, enzymes, enzyme inhibitors, and some components of the extracellular matrix. The important role played by HSPGs has motivated the synthesis and selection of HSPG mimetics for modulating the biological activity of HS-binding proteins. We present hereinafter an efficient polysaccharide microarray method that allows the screening of HS-mimetic libraries towards HS-binding growth factors, a major class of polypeptides whose inhibition or potentiation is of high medical interest.

Abstract
A method for the preparation of carbohydrate microarrays inside 96-well polystyrene microtiter plates is described. The key step in this strategy represents the synthesis of carbohydrate-dextran conjugates by copper (I)-catalyzed [3 + 2] cycloaddition between alkyne carbohydrate derivative and a specially designed azido dextran polymer. The conjugates adsorb efficiently on polystyrene surface and can be printed inside 96-well plates using a non-contact piezoelectric microarrayer. Model interactions with a selection of lectins (concanavalin A, wheat germ agglutinin, Erythrina Cristagalli) display the efficiency of the immobilization method, its reproducibility and the specificity of biomolecular interactions occurring at the polystyrene-water interface.

Abstract
In the last decade, glycan microarrays have revolutionized the analysis of the specificity of glycan-binding proteins (GBPs), providing information that simultaneously illuminates the biology mediated by them and decodes the informational content of the glycome. Numerous methods have emerged for arraying glycans in a "chip" format, and glycan libraries have been assembled that address the diversity of the human glycome. Such arrays have been successfully used for analysis of GBPs, which mediate mammalian biology, host-pathogen interactions, and immune recognition of glycans relevant to vaccine production and cancer antigens. This review covers the development of glycan microarrays and applications that have provided insights into the roles of mammalian and microbial GBPs.

Abstract
Glycan microarrays are emerging as increasingly used screening tools with a high potential for unraveling protein-carbohydrate interactions: probing hundreds or even thousands of glycans in parallel, they provide the researcher with a vast amount of data in a short time-frame, while using relatively small amounts of analytes. Natural glycan microarrays focus on the glycans' repertoire of natural sources, including both well-defined structures as well as still-unknown ones. This article compares different natural glycan microarray strategies. Glycan probes may comprise oligosaccharides from glycoproteins as well as glycolipids and polysaccharides. Oligosaccharides may be purified from scarce biological samples that are of particular relevance for the carbohydrate-binding protein to be studied. We give an overview of strategies for glycan isolation, derivatization, fractionation, immobilization and structural characterization. Detection methods such as fluorescence analysis and surface plasmon resonance are summarized. The importance of glycan density and multivalency is discussed. Furthermore, some applications of natural glycan microarrays for studying lectin and antibody binding are presented.

Abstract
Glycan arrays have become a powerful tool for the high-throughput elucidation of interactions of different carbohydrate structures with a wide variety of biological targets, including antibodies, proteins, viruses and cells. This technique is especially suitable for glycomics studies, because arrays present carbohydrate ligands in a manner that mimics interactions at cell-cell interfaces. This review assesses the recent advances involving glycan arrays, including new methods for glycan-array fabrication, new platforms for novel biological information, and new perceptions of glycomics for improving the understanding of disease-related glycobiology. Furthermore, this review attempts to forecast trends in the development of glycan arrays and possible solutions for some remaining challenges to improve this new technology.

Abstract
Peptide microarrays are useful tools for characterizing the humoral response against methylated antigens. They are usually prepared by printing unmodified and methylated peptides on substrates such as functionalized microscope glass slides. The preferential capture of antibodies by methylated peptides suggests the specific recognition of methylated epitopes. However, unmodified peptide epitopes can be masked due to their interaction with the substrate. The accessibility of unmodified peptides and thus the specificity of the recognition of methylated peptide epitopes can be probed using the in situ methylation procedure described here. Alternately, the in situ methylation of peptide microarrays allows probing the presence of antibodies directed toward methylated epitopes starting from easy-to-make and cost-effective unmodified peptide libraries. In situ methylation was performed using formaldehyde in the presence of sodium cyanoborohydride and nickel chloride. This chemical procedure converts lysine residues into mono- or dimethyl lysines.

Abstract
This way up. Dual polarisation interferometry was used to design and characterise a surface on which the orientation and density of immobilised carbohydrates was suitable for studying their interactions with proteins. Lactoferrin was shown to adopt two orientations: "end-on" or "side-on", while for FGF-2 a single monolayer of protein was observed. The new surface can be used to elucidate the binding of proteins to carbohydrates and the geometry of the complexes, a frequently controversial area. Surface-based tools, such as microarrays and optical biosensors, are being increasingly applied to the analysis of carbohydrate-protein interactions. A key to these developments is the presentation of the carbohydrate to the protein target. Dual polarisation interferometry (DPI) is a surface-based technique that permits the real-time measurement of the changes in thickness, refractive index and mass of adsorbates 100 nm thick or less on the surface of a functionalised waveguide. DPI has been used to design and characterise a surface on which the orientation and density of the immobilised carbohydrates is suitable for studying their interactions with proteins and where nonspecific binding is reduced to less than 5 % of total binding. A thiol-functionalised surface was derivatised with a heterobifunctional crosslinker to yield a hydrazide surface. This was treated with oligosaccharides, derived from keratan sulfate (KS) chondroitin sulfate (CS) and heparin, that possess a reducing end. To block the unreacted hydrazide groups, the surface was treated with an aldehyde-functionalised PEG. The heparin DP-10 surfaces were then used to determine the performance of the immobilised DP-10 with respect to binding of two well-characterised proteins, lactoferrin (Lf) and fibroblast growth factor-2. The results show that Lf could adopt two different orientations, at high protein loadings the protein layer thickness corresponded to an "end-on" orientation of Lf, whilst rinsing with buffer saw the Lf molecules adopt a "side-on" configuration. In the case of FGF-2, a single monolayer of protein bound to DP-10 was observed. These results demonstrate that the new surface can be used to resolve key questions relating to the binding of proteins to carbohydrates, including, when used in DPI, the resolution of the geometry of complexes, an area that is frequently controversial.

Abstract
In the present study, we explored the binding capacity of synthetic heparin-like dextran derivatives to recombinant human bone morphogenetic protein 2 (BMP-2), a heparin-binding osteoinductive growth factor. Affinity electrophoresis analysis provided evidence that carboxymethylated dextran polymers grafted with high amounts of benzylamide groups (named DMCB) interact with BMP-2. The capability of such polysaccharides to potentiate the growth factor biological activity was then investigated. In vitro, DMCB dose-dependently promoted osteoblast differentiation induced by BMP-2 in C2C12 myoblasts more efficiently than heparin. A screening study provided evidence that the potentiating effects of the dextran derivatives on the BMP-2-induced alkaline phosphatase activity improved with their benzylamide groups content and, therefore, with their affinity for the growth factor. The biological activity of BMP-2 was monitored in the culture medium after 6 days using C2C12 cells (containing a BMP sensitive luciferase reporter gene). Like heparin, DMCB sustained the biological activity of the growth factor; this result suggests that the formation of the BMP-2/DMCB complex may protect the protein from being inactivated. In rats in vivo, DMCB also stimulated ectopic calcification mediated by BMP-2. These data indicate that dextran-based polysaccharides prolong the half-life of the growth factor and promote its biological activity.

Abstract
A heparin glycan chip (HepGlyChip) with a 4800-fold enhanced signal-to-noise ratio as compared with the control without heparin was developed for high-throughput analysis of heparin-protein interactions for new drug development and for screening biological samples in diagnostic applications. As a proof of concept, a heparin glycan microarray was prepared on a poly(styrene-co-maleic anhydride) (PS-MA)-coated glass slide. Heparin was covalently immobilized on poly-l-lysine (PLL) layer with multiple binding sites by sulfo-ethylene glycol bis(succinimidylsuccinate) (sulfo-EGS), increasing the signal-to-noise ratio, minimizing nonspecific binding of target proteins, and resulting in a three-dimensional (3D) structure on the HepGlyChip. This on-chip signal amplification platform was successfully demonstrated by probing the heparin microarray with the highly specific heparin-binding protein antithrombin III (AT III).

Abstract
We report a carbohydrate microarray-based approach for the rapid, facile analysis of glycosaminoglycan-protein interactions. The key structural determinants responsible for protein binding, such as sulfate groups that participate in the interactions, were elucidated. Specificities were also readily compared across protein families or functional classes, and comparisons among glycosaminoglycan subclasses provided a more comprehensive understanding of protein specificity. To validate the approach, we showed that fibroblast growth factor family members have distinct sulfation preferences. We also demonstrated that heparan sulfate and chondroitin sulfate interact in a sulfation-dependent manner with various axon guidance proteins, including slit2, netrin1, ephrinA1, ephrinA5, and semaphorin5B. We anticipate that these microarrays will accelerate the discovery of glycosaminoglycan-binding proteins and provide a deeper understanding of their roles in regulating diverse biological processes.
