3'-sialyllactose

3'-Sialyllactose (3'-SL), a prebiotic with anti-inflammatory and anti-arthritic properties, plays a role in maintaining immune homeostasis. As a common carbohydrate with the lowest toxicity level, it is utilized in inflammation research.

3'-Sialyllactose sodium is a prebiotic with anti-inflammatory activity that maintains immune homeostasis. 3'-Sialyllactose sodium reduces stressor-induced anxiety-like behaviors and can be used in studies of inflammation and arthritis.

6'-Sialyllactose consists of the monosaccharide N-acetylneuraminic acid linked to the galactosyl subunit of lactose at the 6 position. This connection is at the 3 position in the related compound, 3’-sialyllactose. Both are major milk oligosaccharides that avidly bind several viral strains, including strains of influenza, HIV-1, reovirus, and polyomavirus.[1],[2],[3],[4],[5],[6] These compounds can be used to differentiate and characterize the binding domains of viruses that recognize N-acetylneuraminic acid-capped cell surface receptors. They are also used as analytical reference standards for quantification in samples such as milk or colostrum. Reference：[1]. Duncan, P.I., Raymond, F., Fuerholz, A., et al.
