CD BioGlyco is committed to providing expert technical support and integrated solutions to help clients use tuftsin to surface modify alginate biomaterials for active targeted delivery to macrophages. Our biodegradable tuftsin-decorated alginate development services have the potential to contribute to targeted drug delivery systems and gene therapy research.

Properties of Alginate and Tuftsin

Alginate is a block copolymer consisting of (1→4)-linked β-D-mannosyluronic acid (M) and α-L-gullosyluronic acid (G) residues and exists in nature as a structural component of marine brown algae (Phaeophyceae). It has been widely used in various industries such as the food, pharmaceutical, and cosmetic industries. The ability of the polymer to form a cross-linked gel-like structure in the presence of polyvalent cations such as Ca²⁺, coupled with its good biocompatibility, low toxicity, and relatively low cost, alginate is considered to be a very useful biomaterial for many fields such as drug and cell delivery.

Tuftsin is a tripeptide composed of L-threonine, L-lysine, L-proline, and L-arginine, which can stimulate the immune function of various cells, especially macrophages. Tuftsin was found to increase macrophage-mediated phagocytosis, splenic cell proliferation, macrophage migration index, and bactericidal and tumoricidal activities. Therefore, the development of biodegradable tuftsin-decorated alginate biomaterials offers the possibility of overcoming the existing problems of poor or low transfection efficiency associated with macrophage-targeted non-viral vectors.

Biodegradable Tuftsin-decorated Alginate Development Services at CD BioGlyco

Given the important role of macrophages in acute and chronic inflammatory responses in vivo, our researchers are working on the development of Other Polysaccharide-based Biodegradable Materials to develop safe and effective non-viral gene delivery strategies for macrophages, including tuftsin-decorated alginate nanoparticles, which could help accelerate research into gene therapy for inflammatory diseases such as rheumatoid arthritis (RA). Our services include but are not limited to:

• Preparation of blank and DNA-encapsulated calcium alginate nanoparticles by an external gel method.
• Surface modification of blank and DNA-encapsulated alginate nanoparticles. We use peptide sequences with tuftsin to modify the surface of the particles.
• Characterization of tuftsin-decorated crosslinked alginate nanoparticles, including particle size, surface charge, and morphology analyses, as well as the determination of the peptide density on the surface of the nanoparticles.
• Evaluation of the uptake and cell internalization of the tuftsin-decorated alginate nanoparticles.

Our Advantages

• Stable and reliable polysaccharide-based biodegradable materials synthesis platform
• Multiple synthesis methods are available
• Customized tuftsin-decorated alginate development service
• One-stop service, 24 hours after-sales service

CD BioGlyco is dedicated to the development of high-quality Polysaccharide-based Biodegradable Materials, including tuftsin-decorated alginate nanoparticles.
