MtoZ Biolabs provides specialized Protein Glycosylation Analysis Service that helps researchers investigate glycosylation modifications in proteins. Glycosylation, one of the most common and complex post-translational modifications, plays a crucial role in protein folding, stability, function, and cellular interactions. Our Protein Glycosylation Analysis Service enables precise mapping of glycosylation sites, identification of glycoforms, and characterization of glycosylation dynamics, all of which are essential for understanding protein function, disease mechanisms, and therapeutic development.
Overview
Glycosylation refers to the attachment of carbohydrate moieties (glycans) to proteins, which significantly influences their structure and biological activity. Glycosylation can occur at different sites, including N-linked (attachment to asparagine residues) and O-linked (attachment to serine or threonine residues), each affecting protein function in unique ways. Dysregulated glycosylation is implicated in various diseases, including cancer, neurodegenerative diseases, and autoimmune disorders.

Protein Glycosylation Analysis Service at MtoZ Biolabs
1. Targeted Protein Glycosylation Analysis
This service is ideal for studying specific glycosylated proteins. Purified proteins or immunoprecipitated complexes are analyzed to identify glycosylation sites, characterize glycan structures, and evaluate any changes in glycosylation due to disease states or treatments.
2. Glycosylation Proteomics
For global discovery, we offer proteome-wide profiling of glycosylated proteins in complex biological samples, such as cell lysates, tissue lysates, or secreted proteins. This service supports discovery research into glycosylation-associated diseases and pathways.

FAQ
Q1: What types of samples are suitable?
We accept purified proteins, immunoprecipitated proteins, cell lysates, tissue lysates, and secreted proteins for qualitative glycosylation identification.
Q2: How should I prepare my samples?
- Keep samples fresh or snap-frozen to prevent modification loss
- Use lysis buffers compatible with glycosylation enrichment, avoiding detergents, high salt, or inhibitors that interfere with glycan capture
- Provide sufficient protein input (~100 µg for targeted workflows; ~500 µg for discovery-level profiling)
- For IP samples, ensure high purity to facilitate accurate site localization
