CD BioGlyco leverages its deep expertise in glycobiology and advanced multi-omics platforms to offer comprehensive services for the assessment of seaweed oligosaccharide-mediated gut microbiota regulation and immune activity. This cutting-edge service is essential for researchers and biotech companies seeking to scientifically validate the prebiotic and immunomodulatory effects of their seaweed-derived compounds, leading to evidence-based product development and successful lead generation.
Key Technologies
Advanced Glycobiology Characterization
Utilizing proprietary technologies for the precise structural characterization and purification. This includes high-performance liquid chromatography (HPLC), mass spectrometry (MS), and nuclear magnetic resonance (NMR) to ensure the exact nature of the test compound is known.
High-Resolution Metabolomics
Utilizing ultra-performance liquid chromatography-MS (UPLC-MS/MS) to quantify critical gut microbial metabolites, such as short-chain fatty acids (SCFAs-acetate, propionate, butyrate), secondary bile acids, and amino acid derivatives.
High-Throughput Immunological Assays
Employing flow cytometry, ELISA, and multiplex cytokine/chemokine profiling on various in vitro (e.g., immune cell lines, primary immune cells) and in vivo (e.g., serum, splenocytes) samples to precisely measure the immunomodulatory effects of the test compounds.
Validate Your Marine Glyco-Bioactive for Gut Health & Immune Resilience
Our service is meticulously designed to provide an evidence-based pathway for translating marine-derived carbohydrate research into high-value applications. We provide comprehensive services covering two major, interconnected areas:
- Gut Microbiota Regulation Assessment of Seaweed Oligosaccharide
- Microbial Composition Analysis: High-resolution profiling of the gut microbiome to track changes in diversity, species richness, and the relative abundance of phyla, families, and genera. We specialize in detecting targeted changes, such as the increase of SCFA-producers or mucus-degraders.
- Functional Profiling: Absolute quantification of key microbial metabolites, primarily SCFAs. We also assess other significant metabolites, including secondary bile acids and tryptophan catabolites, which are known to influence intestinal barrier function and immunity.
- Immune Activity Assessment of Seaweed Oligosaccharide
- Cytokine and Chemokine Profiling: Measurement of a comprehensive panel of pro- and anti-inflammatory cytokines in serum, mucosal washes, or cell culture supernatants using sensitive multiplex platforms.
- Immune Cell Phenotyping and Activation: Using multi-color flow cytometry, we analyze crucial immune cell populations in peripheral blood and mucosal-associated lymphoid tissues (GALT).
- TLR/PRR Signaling Pathway Analysis: Evaluation of the compound's ability to directly stimulate or inhibit key pattern recognition receptors (PRRs) like Toll-like receptors (TLRs) on immune cells, offering insight into the direct mechanism of immune modulation.
Workflow
1. Compound Characterization
We verify purity, molecular weight distribution, and composition (e.g., monosaccharide profile, degree of sulfation) to ensure experimental reproducibility and to establish crucial structure-function relationships.
2. In Vitro Prebiotic Screening
Simulated gastric and intestinal fluid models are used to assess the selective growth promotion of specific beneficial bacteria strains and the resulting production of key metabolites under controlled conditions.
3. In Vivo Model Establishment
To model the complex host-microbe interaction, we employ appropriate in vivo models (e.g., mouse models with diet-induced dysbiosis, germ-free models, or specific disease models like colitis or allergy).
4. Gut Microbiota Profiling
Fecal and cecal contents are collected to perform 16S rRNA sequencing and shotgun metagenomics for microbial community shifts analysis. This data is complemented by metabolomic analysis to quantify the functional outputs.
5. Immune Activity Assessment
Immune tissues and peripheral blood are analyzed to quantify changes in immune cell populations using flow cytometry. ELISA or multiplex array is used to measure systemic and mucosal cytokine levels to pinpoint the anti-inflammatory mechanisms.
6. Comprehensive Reporting
Advanced bioinformatics tools are utilized to correlate specific structural features of the oligosaccharide with changes in microbial taxa, metabolite profiles, and host immune status. A comprehensive report with clear visualizations and mechanistic interpretations is provided.

Results: This review explores the potential of seaweed and its functional metabolites (polysaccharides, polyphenols, pigments, omega-3s) as sustainable aquafeed additives to modulate fish growth, immunity, antioxidant capacity, and gut microbiota. Seaweed's nutritional profile varies by type—red seaweed has the highest protein, while brown seaweed is rich in polysaccharides like fucoidan, and green seaweed contains ulvan. Low dietary inclusion enhances fish growth, feed utilization, and disease resistance by boosting lysozyme activity, antioxidant enzymes, and beneficial gut bacteria. It also improves intestinal morphology. However, high inclusion causes growth suppression due to antinutrients and reduced palatability.

Frequently Asked Questions
How long does a full, integrated gut-immune assessment typically take?
A standard, comprehensive project—from in vivo model initiation through to final multi-omics data interpretation—typically ranges from 12-16 weeks. We will provide a precise timeline after a consultation on your specific experimental design.
My oligosaccharide has unique structural features (e.g., specific sulfation). Can you accommodate this?
Yes, this is our specialty. We begin with a structural characterization to understand these unique features and then tailor the subsequent biological assays to test hypotheses based on that structure, ensuring a highly relevant and targeted study.
