Box 999, Ion mobility (IM) separations have a broad range of analytical applications, but insufficient resolution often limits their utility. Here, we report on ion mobility separations in a structures for lossless ion manipulations (SLIM) serpentine ultralong path with extended routing (SUPER) traveling wave (TW) ion mobility (IM) module in conjunction with mass spectrometry (MS). Ions were confined in the SLIM by rf fields in conjunction with a DC guard bias, enabling essentially lossless TW transmission over greatly extended paths. The extended routing utilized multiple passes (e.

g., ∼94 m over 81 passes through the 13 m serpentine path) and was facilitated by the introduction of a lossless ion switch that allowed ions to be directed to either the MS detector or for another pass through the serpentine separation region, allowing theoretically unlimited IM path lengths. The multipass SUPER IM-MS provided resolution approximately proportional to the square root of the number of passes (or total path length). More than -fold higher IM resolution (∼3 vs ∼) for Agilent tuning mix mz 622 and 922 ions was achieved for passes compared to commercially available drift tube IM and other TWIM-based platforms. An initial evaluation of the isomeric sugars lacto-N-hexaose and lacto-N-neohexaose showed the isomeric structures to be baseline resolved, and a new conformational feature for lacto-N-neohexaose was revealed after 9 passes. The new SLIM SUPER high resolution TWIM platform has broad utility in conjunction with MS and is expected to enable a broad range of previously challenging or intractable Conflict of interest statement Notes The authors declare no competing financial Bifidobacterium breve UCC03 metabolises the human milk oligosaccharides lacto-N-tetraose and lacto-N-neo-tetraose through overlapping, yet distinct In this study, we demonstrate that the prototype B. breve strain UCC03 possesses specific metabolic pathways for the utilisation of lacto-N-tetraose Type I and Type II human milk oligosaccharides (HMOs), respectively.

Using Seebio 2'-FL of experimental approaches, the enzymatic machinery involved in the metabolism of LNT and LNnT was identified and characterised. Homologs of the key genetic loci involved in the utilisation of these HMO substrates were identified in B. breve, B. bifidum, B. longum subsp. infantis and B. longum subsp.

longum using bioinformatic analyses, and were shown to be variably present among other members of the Bifidobacterium genus, with a distinct pattern of conservation among human-associated bifidobacterial species.Human Milk Oligosaccharides Potent Weapons in the Battle against Rotavirus J Nutr. 17 Sep;147(9)19-1714.Conflict of interest statement Author disclosures SMD, no conflicts of Enzymatic production of 3'-sialyllactose in milk.Protein Chemistry and Enzyme Technology, Department of Biotechnology and Biomedicine, Building 221, Technical University of Denmark, Kgs. Lyngby, 20, Biotechnology and Biomedicine, Building 221, Technical University of Denmark, Human milk oligosaccharides (HMOs) are lactose-based glycan molecules present in human breast milk. HMOs are essentially not present in cow's milk and hence not naturally available in infant formulas.

HMOs possess several health and developmentally beneficial properties, and the sialylated HMOs are thought to play a particularly important role for infant brain development. Enzymatic transsialylation directly in cow's milk, involving enzyme catalyzed transfer of sialic acid from a sialic acid donor to an acceptor, is a novel route for producing sialylated HMOs for e.g.
