Oligosaccharides – Summary of Our Services
Glycans of glycoproteins and oligosaccharides consist of complex sugar compounds which may be linear or branched. They differ in length, composition of monosaccharides and their physiological significance. For unravelling the sugar code, we offer a variety of analytical solutions.
Whether cosmetic products or food, we determine the composition of oligosaccharides in raw materials and final products. You assure the constant quality of your raw materials with our service. State-of-the-art infant formula contains oligosaccharides in the form of GOS and FOS (galacto-oligosaccharides and fructo-oligosaccharides). Additionally, breast milk is rich in bound sialic acid (e.g. sialyllactose). Learn more about our sialic acid analysis.
Glycoproteins usually contain many different glycan structures. Using glycan profiling we are able to generate characteristic fingerprints. Composition and variation of glycan structures can be exactly identified.
Lectins selectively identify linking of complex glycans and can therefore distinguish between bound glycans and free glycans. The GlycoImage® sialic acid ELISA is devised specifically for the differentiation of bound and free sialic acid in milk powder for infant formula.
