Description

6'-Sialyllactose is a sialylated human milk oligosaccharide that can promote the proliferation of bifidobacteria and shaping the gut microbiota. 6'-Sialyllactose also inhibits toll-like receptor 4 signaling and protects against the development of necrotizing enterocolitis[1][2].

In Vitro

6'-Sialyllactose (10 mg/mL; supplementation of infant formula) prevent necrotizing enterocolitis (NEC) in mice in a dose-dependent manner[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
