Keratan Sulfate (KS) contains a disaccharide unit consisting of galactose and 6-position O-sulfated acetyl glucosamine residues. The hydroxyl groups beyond the 6-position of the acetylglucosamine residue of Marine Carbohydrate-derived KS are further sulfated, resulting in the formation of polysulfated keratan sulfate. Therefore, KS from Marine Animals has stronger anti-inflammatory and immunosuppressive effects. Based on this property, CD BioGlyco offers a professional KS-based drug-delivery vehicle development service to clients.
KS-based Drug-Delivery Vehicle Development Service at CD BioGlyco
CD BioGlyco has a professional Marine Carbohydrate-based Drug-Delivery Vehicle development team. We offer the following services:
- KS Preparation and Physicochemical Property Determination
We efficiently separate KS and impurities by combining an ion exchange column and high-performance liquid chromatography (HPLC). For purified KS, we provide component identification services such as glucuronic acid content analysis, molecular weight determination, organic sulfate determination, etc. Notably, high-purity KS is key to the success of the subsequent drug-delivery vehicle.
- Synthesis and Characterization Service
We provide a variety of keratan sulfate-based drug-delivery vehicle synthesis services such as nanoliposomes, microspheres, microcapsules, nanoparticles, etc. These forms of drug-delivery vehicles greatly improve the convenience of medication and increase the efficacy while reducing the side effects. Our research group continuously optimizes production conditions through orthogonal design, focusing on evaluating the effects of solution concentration, pH, molecular weight, and others on drug-delivery vehicle synthesis.
For keratan sulfate-based drug-delivery vehicles, we provide a range of characterization services e. g., vehicle volume, surface potential, etc. In addition, we offer Fourier transform infrared spectrometer (FTIR) analysis, nuclear magnetic resonance (NMR) analysis, and dynamic light scattering (DLS) analysis services.
- In Vitro Analysis Service
Our talented team has extensive experience in bioactivity analysis. The in vitro drug release efficiency of the drug-delivery vehicle is measured by dialysis. At a predetermined time point, the medium is sampled to calculate the cumulative release of the drug. Meanwhile, we care a lot about in vitro cytotoxicity assay service. We compare the in vitro cytotoxicity of cancer cells and blank group by MTT assay. In addition, we use flow cytometry to provide cellular uptake mechanism study services. Our analysts help our clients to fully analyze the data processing and provide professional analysis reports for them.
- In vivo activity analysis service
By making the animal model, we set up the model group, positive control group, negative control group, and sample administration group, and gave drugs and tested different indicators to determine the effect.
