Lacto-N-tetraose is the significant core structure of human milk oligosaccharides (HMOs) naturally existing in human milk. Lacto-N-tetraose is consist of galactose, N-acetylglucosamine, and glucose moieties. Lacto-N-tetraose has prebiotic effect, immune regulatory effect, anti-inflammatory effects, intestinal cell responses regulatory effect, antibacterial activity and antiviral activity. Lacto-N-tetraose has been widely added to infant formula.

Description

Lacto-N-tetraose is the significant core structure of human milk oligosaccharides (HMOs) naturally existing in human milk. Lacto-N-tetraose is consist of galactose, N-acetylglucosamine, and glucose moieties. Lacto-N-tetraose has prebiotic effect, immune regulatory effect, anti-inflammatory effects, intestinal cell responses regulatory effect, antibacterial activity and antiviral activity. Lacto-N-tetraose has been widely added to infant formula[1].

In Vitro

HMOs exhibits antimicrobial and antibiofilm activity against Streptococcus agalactiae, antibiofilm activity against Methicillin-resistant Staphylococcus aureus (MRSA), and antimicrobial activity against both Acinetobacter baumannii and Clostridium difficile[2].
Lacto-N-tetraose (500-2000 μg/mL) does not cause clastogenic or aneugenic signs in human peripheral blood lymphocytes, nor increase the percentage of micronucleated cells[3].

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.
