Glycoprotein Microarray Service utilizes high-density microarray technology to immobilize glycoproteins on chip surfaces for the detection of their binding characteristics and functional specificity with molecules such as antibodies, lectins, receptor proteins, or pathogen-associated factors. This service is applicable to antibody screening, glycosylation function analysis, disease-related glycoprotein biomarker identification, and vaccine antigen discovery, providing powerful technical support for research in glycomics, immunology, and translational medicine.
Glycoproteins are widely distributed on the cell membrane, in the extracellular matrix, and in bodily fluids. Their glycosylation modifications play essential regulatory roles in protein folding, localization, stability, and molecular recognition. In various pathological conditions such as cancer, infection, autoimmunity, and neurodegenerative diseases, glycoproteins often undergo significant structural and functional alterations, making them highly valuable as biomarkers and therapeutic targets.
The glycoprotein microarray is a high-throughput analytical platform that immobilizes structurally defined glycoproteins onto a solid-phase chip and detects their interactions with labeled molecules (e.g., antibodies, lectins, receptor proteins, cytokines). This technology enables functional profiling, interaction mapping, and disease relevance assessment of glycoproteins. It combines the multifunctionality of protein microarrays with the specific recognition capacity of glycomics, making it suitable for research in immunology, oncology, infectious biology, and beyond.
MtoZ Biolabs offers Glycoprotein Microarray Service to systematically analyze the interactions between glycoproteins and various recognition molecules, such as antibodies, lectins, receptor proteins, and pathogen factors. This service supports antibody screening, glycosylation-related functional studies, biomarker discovery, and vaccine antigen identification. We offer customizable glycoprotein array design and parallel sample detection to facilitate efficient elucidation of structure-function relationships of glycoproteins and their critical roles in disease mechanisms.

Analysis Workflow
The main workflow of the Glycoprotein Microarray Service is as follows:
1. Sample Preparation
Glycoproteins are extracted while ensuring structural integrity and stability of glycosylation states.
2. Microarray Chip Construction
Glycoproteins are immobilized onto the chip surface using high-precision spotting techniques to create a high-density, low-background detection platform.
3. Incubation with Recognition Molecules
Labeled recognition molecules (such as antibodies, lectins, or receptor proteins) are incubated with the chip to capture specific glycoprotein-molecule binding events.
4. Signal Detection and Scanning
Fluorescent or enzyme-labeled systems are used for high-resolution scanning to obtain binding signal images and quantitative data.
5. Data Analysis and Reporting
Bioinformatics tools are applied to perform signal normalization, binding profile analysis, and functional annotation, resulting in a comprehensive data report and visualized output.
