Structure elucidation of sulphated oligosaccharides from recombinant human tissue plasminogen activator expressed in mouse epithelial cells.

abstract：:Human milk oligosaccharides (HMOS) are not digested in the proximal intestine. In distal intestine, HMOS collectively modify the microbiota, but the response of individual bacteria to individual components of the HMOS is not well defined. Here, each of 25 major isolates of the human intestinal microbiota was fed indiv...
