Glycan Arrays
Glycan arrays are indeed powerful tools for high-throughput analysis of glycan-protein and glycan-glycan interactions. These arrays consist of a diverse library of defined glycans covalently attached to a solid support, such as a glass slide or microarray chip, in a spatially defined arrangement
Key advantages of glycan arrays include:
High-throughput screening: Analyze thousands of distinct samples in parallel on a small chip, significantly reducing time and resource requirements
Sensitivity and specificity: Detect and quantify binding events with high precision, even for low-abundance glycans
Versatility: Applicable to a wide range of studies, including lectin and antibody binding specificity, pathogen detection, drug target screening, and biomarker discovery
Minimal sample requirements: Requires only minuscule amounts of each carbohydrate, preserving precious biological samples
Comprehensive analysis: Facilitates the study of interactions with a diverse range of glycans in a single assay
Glycan arrays can incorporate various types of glycans, including N-glycans, O-glycans, and glycolipids, allowing for comprehensive profiling of the glycome1. The choice of array depends on factors such as attachment chemistry (e.g., NHS ester, amine coupling), glycan density, and the specific structures printed
Applications of glycan arrays include:
Characterizing binding specificities of lectins, antibodies, and other glycan-binding proteins
Identifying natural ligands and developing probes/inhibitors for lectins
Studying host-pathogen interactions, including viral and bacterial binding to host glycans
Profiling enzyme specificities, such as glycosyltransferases and glycosidases
Biomarker discovery and development of carbohydrate-based vaccines
Glycan arrays provide quantitative data on binding affinities and specificities, enabling researchers to extract valuable information about glycan-protein interactions. This technology has significantly advanced the field of glycomics and continues to evolve, offering new insights into the complex world of carbohydrate biology
The glycan arrays help researchers:
Identify the glycans binding partners in biological samples.
Identify whether target proteins are carbohydrate binding proteins.
Probe binding of viruses and whole cells to glycans.
Profile the substrate specificity of enzymes (glycosyltransferases, glycosidases, etc.).
Profile the inflammatory immune response.
Immobilized Molecule: Sugar Moieties (Glycans)Species Detected: Not species specific
Lectin arrays leverage the specific binding properties of lectins, carbohydrate-binding proteins, to profile the glycan composition of complex samples. Our lectin arrays offer a diverse collection of lectins with varying specificities for different glycan structures. This allows for a comprehensive analysis of the glycome, revealing subtle changes in glycosylation patterns associated with disease states or other biological processes. The high-throughput nature of our arrays enables rapid screening of multiple samples, significantly accelerating research. Data analysis is streamlined through our user-friendly software, providing clear visualizations and quantitative measurements of lectin-glycan interactions. This allows researchers to identify specific glycan biomarkers and gain insights into the roles of glycosylation in various biological contexts. The advantages include high throughput, sensitivity, and a broad glycan coverage, enabling detailed glycomic profiling in a variety of applications from disease diagnostics to fundamental glycobiology research.
Lectins are glycan-binding proteins which have been purified from trees, beans and some fruits. They are highly specific for a given glycan based on their sequence and the different sugar unit structures the glycan contains. The RayBiotech lectin arrays provide a powerful new tool for glycosylation determination, drug discovery and biomarker development; all with limited samples volumes required.

Glycome Arrays
Glycome Arrays allow researchers to efficiently obtain glycosylation profiles in their samples. Capture antibodies are printed onto glass slides and the glycans on these capture antibodies are removed. The glass slide arrays come pre-blocked and are ready to be incubated with samples. After incubation with samples and washing to remove unbound proteins, five unique biotin-labeled lectins are incubated with the array to allow binding to the glycans from captured target proteins. Streptavidin-conjugated fluorescent dye (Cy3 equivalent) is then added to the array. Finally, the glass slide is dried and laser fluorescence scanning is used to visualize the signals. These signals are then compared to the array map to identify glycosylated proteins present in the samples.
