6'-Sialyllactose (sodium salt)

6'-Sialyllactose consists of the monosaccharide N-acetylneuraminic acid (Cay-16091) linked to the galactosyl subunit of lactose at the 6 position. This connection is at the 3 position in the related compound, 3'-sialyllactose (Cay-16617). Both are major milk oligosaccharides that avidly bind several viral strains, including strains of influenza, HIV-1, reovirus, and polyomavirus. 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.Formal Name: O-(N-acetyl-alpha-neuraminosyl)-(2->6)-O-beta-D-galactopyranosyl-(1->4)-D-glucose, monosodium salt.
