Glycosylated Protein Biomarkers Services

Fig.1 Various types of glycosylated proteins.

Glycosylation is a prevalent and biologically significant post-translational modification. Aberrant glycosylation patterns have been widely documented in a variety of diseases, including cancer, diabetes, liver dysfunction, autoimmune disorders, and infectious diseases. Consequently, glycosylated protein biomarkers, especially glycosylated albumin, ferritin, HCG, and membrane proteins, have garnered heightened interest in the fields of diagnostic and therapeutic development. At Creative Biolabs, we provide integrated solutions for glycoprotein biomarker development, covering discovery, characterization, and functional validation. Our platform combines advanced glycoproteomics technologies with bioinformatics to support the identification and verification of disease-specific glycoprotein biomarkers.

Biological Relevance of Glycosylated Protein Biomarkers

Glycosylated proteins reflect both physiological and pathological changes. Their altered glycan structures can modulate immune recognition, affect serum half-life, or promote oncogenic transformation. For example:

• In cancer, fucosylation and sialylation changes in glycoproteins support immune evasion and metastasis.
• In diabetes, glycated albumin provides short-term glucose monitoring superior to HbA1c in certain populations.
• In pregnancy and trophoblastic diseases, abnormal glycosylation of HCG alters hormone activity and receptor interaction.

Glycosylated biomarkers serve as sensitive readouts of disease states in different conditions. Leveraging extensive expertise in glycoprotein biomarker discovery, Creative Biolabs conducts comprehensive research encompassing oncological disorders, autoimmune conditions, and neurodegenerative diseases:

• Glycoprotein biomarkers in cancer research
• Glycoprotein biomarkers in autoimmune disease research
• Glycoprotein biomarkers in neurodegenerative disease research

Our Glycosylated Protein Biomarker Workflow

Creative Biolabs offers a full-spectrum, research-oriented workflow to support the development, validation, and characterization of glycosylated protein biomarkers. From target identification to functional evaluation, each phase is driven by analytical depth, experimental customization, and expert consultation.

1. Target Consultation & Feasibility Assessment
   We begin by reviewing your target protein(s), research objectives, and biological context. Our glycoscience team helps define feasible strategies based on available data, predicted glycosylation sites, and relevant disease or pathway associations.
2. Sample Preparation & Glycoprotein Isolation
   We process a wide range of biological materials—such as serum, plasma, cell culture supernatants, or tissue lysates—to isolate and enrich glycosylated proteins or peptides.
3. Glycosylation Site Mapping
   This step involves identifying specific N-linked or O-linked glycosylation sites on the protein of interest. It provides residue-level resolution of where glycans are attached.
4. Glycan Structure Characterization
   We determine the exact glycan structures attached to your protein—linkage types, branching patterns, and terminal modifications such as sialylation or fucosylation.
5. Quantitative Glycoproteomics
   To evaluate differential glycosylation under various experimental conditions, we offer relative and absolute quantification of glycoforms using label-based or label-free techniques.
6. Functional Evaluation of Glycoforms
   Glycosylation often alters protein activity, binding affinity, or immunogenicity. We offer a range of biological assays to test the impact of glycoform variation on function.
7. Assay Validation & Reproducibility Testing
   To ensure the reliability of your biomarker findings, we assess intra- and inter-batch consistency, cross-sample reproducibility, and biological variation.
8. Data Interpretation & Reporting
   We provide complete, annotated datasets, including glycan structures, glycosylation site positions, and comparative abundance statistics. Our reports are designed to be publication-ready and integrable into bioinformatics pipelines.
