N-Glycan Profiling Services
- Protein extraction and purification (removal of lipids and salts).
- Mild enzymatic cleavage (PNGase F) to release intact N-glycans, preventing artificial modifications such as desialylation.
- Glycosylation consistency assessment for monoclonal antibody drugs (e.g., PD-1 inhibitors) to optimize ADCC effects.
- Glycan profile comparison of biosimilars (core fucosylation, galactosylation rates).
N-Glycans are complex carbohydrate chains covalently attached to the asparagine (Asn) residues of proteins. They participate extensively in key biological processes such as cell recognition, signal transduction, and immune regulation. Because their dynamic modification patterns can sensitively reflect disease states, drug responses, and aging processes, N-glycans hold great promise as biomarkers and targets for quality control in drug development. Built on a world-leading mass spectrometry platform, MtoZ Biolabs’ N-Glycan Profiling Services offer a one-stop solution that fully characterizes the composition, structure, and abundance of N-glycans from minimal sample volumes, helping researchers uncover the pivotal role of glycosylation in disease mechanisms, diagnostics, and therapies—and accelerating biomarker discovery and biopharmaceutical R&D.

Case Study
1. Highly-Sensitive Label-Free Deep Profiling of N-Glycans Released from Biomedically Relevant Samples
This study developed a highly sensitive, label-free method based on capillary zone electrophoresis-mass spectrometry (CZE-MS) for analyzing native N-glycans released from biomedically relevant samples. Compared to conventional CZE-MS approaches, this workflow achieves over a 45-fold increase in signal intensity. Qualitative and quantitative profiling of N-glycans in human serum IgG, bovine serum fetuin, bovine pancreatic RNase B, blood-derived extracellular vesicles, and total plasma resulted in the identification of >250, >400, >150, >310, and >520 N-glycans, respectively, with minimal sample requirements (as low as 0.2 nL plasma volume equivalent). Additionally, this method enables the identification of highly sialylated N-glycans and the differentiation of untreated sialic acid linkage isomers, facilitating high-sensitivity deep glycan analysis. The N-Glycan Profiling Services provide highly sensitive N-glycan analysis, capable of detecting and profiling N-glycans in various biological samples. It is applicable to proteomics, glycomics, and disease research, delivering precise data support for biomedical studies.

2. Non-Targeted N-Glycome Profiling Reveals Multiple Layers of Organ-Specific Diversity in Mice
This study presents a comprehensive N-glycome dataset from 20 different mouse tissues, demonstrating a multimodal data analysis workflow that provides deep and broad coverage of N-glycan features. The LC-MS/MS data-driven method integrates automated N-glycan identification, non-targeted profiling, and isomer-sensitive analysis. This approach revealed tissue-specific glycosylation patterns, non-canonical N-glycan structures, and highlighted the complex regulation of glycobiological pathways across organs. The research uncovers multiple layers of N-glycome complexity that are governed by organ-specific regulations. Our N-Glycan Profiling Services offer advanced N-glycan profiling, capable of analyzing complex glycosylation patterns in a wide range of biological samples. Using cutting-edge LC-MS/MS techniques, we provide deep and comprehensive N-glycome profiling, including isomer-sensitive glycan structural identification. It is ideal for uncovering tissue-specific glycosylation differences and exploring the regulatory complexity of glycobiological pathways in health and disease.
