Products
Sussex Research has developed a modern glyco product portfolio designed to help researchers explore glycobiology for glycotherapeutic applications. We translate complex carbohydrate chemistries into unique, leading-edge products designed to help researchers explore and exploit glycobiology with a view to advancing the field and creating new biomedical applications that advance human health.
Biotinylated Ligands
Biotinylated Ligands
Biotinylated glycans are emerging as a valuable class of carbohydrate or glycoconjugate probes that allow exploitation of the strong affinity of avidin and streptavidin for biotin, a feature vastly utilized across molecular biology for decades. Techniques for the study of protein–carbohydrate interactions are of great interest in glycobiology and to this day, Sussex Research Laboratories Inc. has been developing biotinylated saccharides to advance research in the field.
Carbohydrate Ligands
Carbohydrate Ligands
Sussex Research Laboratories Inc. is the leading commercial source of synthetic, well-defined carbohydrate ligands. These are multi-purpose, functionalized products that enable researchers to modify virtually any molecule, large or small, with carbohydrates via simple discrete, monodisperse polyethylene glycol (PEG) or alkyl linker/spacer systems. In contrast to traditional alkyl linker/spacers, PEG linker/spacers are water soluble and amphiphilic which reduces linker hydrophobic interactions with macromolecules and surfaces.
GalNAc Ligands
GalNAc Ligands
Sussex Research Laboratories Inc. has developed an extensive selection of functionalized GalNAc ligands with various alkyl and/or polyethylene glycol (PEG) linker/spacer systems. These enable facile introduction of GalNAc-based recognition elements onto a variety of molecules including but not limited to small molecules, surfaces, nanoparticles, peptides, proteins, antibodies, lipids and oligonucleotides.
Glucuronide Metabolites
Glucuronide Metabolites
In nature, glucuronidation is one of the main phase 2 metabolic pathways by which an organism transforms a small molecule drug or xenobiotic into a more water-soluble substance which may be responsible for a drug’s therapeutic affect but certainly enable its detoxification and further excretion. Glucuronides are formed enzymatically by the UDP-Glucuronosyltransferases which have been reported active in the liver, kidneys, epithelial cells of the lower gastrointestinal tract and the brain.
Glycoamino Acids
Glycoamino Acids
Sussex Research Laboratories Inc. has provided researchers with the most extensive selection of commercially available, high purity glycosylated amino acids (glycoamino acids). In nature, protein glycosylation, forming glycosylated proteins or glycopeptides, is a fundamental posttranslational modification process that controls protein shape, half-life and essential biological pathways ranging from protein trafficking to cell adhesion. Glycoamino acids are the basic sites of protein glycosylation, most commonly occurring at serine and threonine in the case of O-linked proteins, and at asparagine (Asn) in the case of N-linked glycoproteins.
Glycopeptides
Glycopeptides
Glycopeptides offer a unique frontier for research & development. The critical role of glycan elements on cell surface proteins and those bound to circulatory proteins is well recognized. Carbohydrates on proteins mediate a host of biological events including cell adhesion, immune system function, fertilization, cellular targeting as well as protein transport, stabilization, and half-life. Thus, the use of synthetic glycoproteins or their fragments (glycopeptides) as experimental probes for basic research and biomedical applications is growing rapidly.
Mono, Oligo & Polysaccharides
Mono, Oligo & Polysaccharides
Sussex Research Laboratories Inc. prides itself on its ability to synthesize, purify and fully characterize complex carbohydrate systems such as oligosaccharides. From blood group to GAG oligosaccharides, we are experienced in virtually all aspects of oligosaccharide synthesis. The company has an excellent infrastructure including in-house high field NMR and mass spectrometry facilities for structural validation. We use chemical, enzymatic and chemoenzymatic approaches to synthesize our oligosaccharides.

Tools, Click Chemistry & Probes
As glycan features are determined on lipids and proteins within complex biological systems, it’s important to translate these findings into useful products that help advance the science in practical ways or offer new therapeutic targets to treat diseases, effect delivery of therapeutic payloads or create new biomarkers to diagnose and prognose diseases.
Reference Standards
Reference Standards
Sussex Research Laboratories Inc. synthesizes reference standards which are routinely used for quantitation and qualification of API (Active Pharmaceutical Ingredient), Metabolites and NCE’s (New Chemical Entity), as well as for Internal Standards in bioanalytical methods. These include stable isotopes (deuterated, 13C and 15N), glucuronides, metabolites & impurities.
Vitamin Standards
Vitamin Standards
These synthetic stable isotope-labelled vitamin D2, D3, E and cholesterol products, along with their hydroxy metabolites, are of the highest quality and used by researchers worldwide. These stable isotope-labelled standards are optimal for use as gold standard analytical standards and as such are trusted in the analytical protocols of global nutrition companies and bioanalytical contract research organizations on five continents.
