Profile: Sussex Research Laboratories, Inc. specializes in carbohydrate and custom synthesis. Our products include glycoamino acids, glycopeptides, linker/spacer glycosystems, oligosaacharides, pseudaminic acids and modified carbohydrates. Our PEGylated glycosides are multi-purpose functionalized products that enable researchers to modify macromolecules, surfaces and nanostructures with carbohydrates via simple polyethylene glycol (PEG) linker systems. These glycosides are used as carbohydrate carriers in glycotherapeutic applications, drug carriers for site specific delivery, drug enhancers for decreasing toxicity and solubility & protein enhancers. The pseudaminic acid is a sialic acid-like saccharide. It is observed in other organisms including the gastrointestinal pathogens such as helicobacter pylori and campylobacter.
