Analysis of nonderivatized neutral and sialylated oligosaccharides by electrospray mass spectrometry
Huang L, Riggin R
Anal Chem
. 2000 Aug;
72(15):3539-46.
PMID: 10952540
An HPLC/MS method has been developed that allows rapid, direct analysis of underivatized sialylated as well as neutral oligosaccharides. The method involves the separation of oligosaccharides from salts and proteins...

In the presence of bacitracin, vancomycin-resistant Enterococcus faecium (vanA phenotype) accumulate UDP-N-acetylmuramyl(UDP-Mur-NAc)-tetrapeptide and a UDP-MurNAc-depsipentapeptide containing lactate substituted for the carboxy-terminal-D-alanine residue. In an in vitro peptidoglycan polymerization assay, the...
