Cell Surface Sialic Acid Glycoengineering Service

Importance of Sialic Acid

Sialic acid is a type of α-keto acid sugar with a nine-carbon backbone, which is widely distributed in animal tissues. The sialic acid family includes various derivatives of the nine-carbon sugar neuraminic acid, which is applied as components of oligosaccharide chains of mucins, glycoproteins, and glycolipids, and they decorate the ends of sugar chains on the surface of cells or soluble proteins. The occurrence of many diseases is related to abnormal sialic acid modification on the cell surface. By performing sialic acid engineering services on the cell surface, these abnormalities are simulated or repaired to study the role of sialic acid in the pathogenesis of different diseases and explore treatments targeting sialic acid modifications.

Cell Surface Sialic Acid Glycoengineering Service at CD BioGlyco

CD BioGlyco provides professional cell surface sialic acid glycoengineering service, which is a technology that changes the characteristics and functions of cells by modifying the sialic acid glycosyl structure on the cell surface. We use chemical synthesis methods or enzyme-catalyzed reactions to directionally add sialic acid or specific types of sialic acid derivatives on the cell surface, which change the sialic acid modification level and structure of the cell surface to change its biological activity and interactions. We also adjust the structure of cell surface sialic acid, such as changing chain length, modification group type, etc., to achieve specific modifications of cell surface sialic acid. The main types of services provided are as follows.

CD BioGlyco provides efficient sialic acid glycan analysis services. We use various analytical techniques, such as mass spectrometry, chromatography, and nuclear magnetic resonance, to conduct qualitative and quantitative analysis of modified or synthesized sialic acid glycans to evaluate the effects of sialic acid glycoengineering.

In addition, CD BioGlyco also provides the design and synthesis of sialic acid-specific probes. We provide sialic acid-specific probes with high selectivity and affinity for localization, detection, and visualization of sialic acid modifications on the cell surface.

Applications

• Immunotherapy: Sialic acid glycoengineering changes the structure of sialoglycos on the surface of immune cells and enhances or inhibits their interactions with other cells or molecules to regulate immune responses.
• Vaccine development: Sialic acid on the cell surface is an important antigen for many pathogens. By mimicking or targeted modification of sialic acid, vaccine candidates are developed to stimulate specific immune responses and improve the immune system's ability to recognize and attack specific pathogens.
• Drug screening: The importance of sialic acid in cellular function and interactions makes it a potential drug target. Through sialic acid glycoengineering services, drugs modified by sialic acid on the cell surface are screened, which provides new ways for disease treatment and drug development.
