Characterisation of brewpub beer carbohydrates using high performance anion exchange chromatography coupled with pulsed amperometric detection.[Pubmed: 24001825 ]
High performance anion exchange chromatography (HPAEC) coupled with pulsed amperometric detection (PAD) was optimised in order to quantify mannose, maltose, maltotriose, Maltotetraose, maltopentaose, maltohexaose and maltoheptaose content of beer.
METHODS AND RESULTS:
The method allows the determination of above mentioned oligosaccharides, in a single chromatographic run, without any pre-treatment. Limit of detection and limit of quantification were suitable for beer. Accuracy and repeatability were good for the entire amount considered. Once optimised HPAEC PAD for the specific matrix, the second goal of this research was to verify the possibility to discriminate beers, depending on their style. The carbohydrates content of brewpub commercial beers was very variable, ranging from 19.3 to 1469mg/L (mannose), 34.5 to 2882mg/L (maltose), 141.9 to 20731mg/L (maltotriose), 168.5 to 7650mg/L (Maltotetraose), 20.1 to 2537mg/L (maltopentaose), 22.9 to 3295mg/L (maltohexaose), 8.5 to 2492mg/L (maltoeptaose), even in the same style of beer. However, the carbohydrates content was useful, jointed with other compounds amount, to discriminate different styles of beer. As a matter of fact, principal component analysis put in evidence beer differences considering some fermentation conditions and colour.

Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Inhibition of PDGF-induced migration and TNF-α-induced ICAM-1 expression by maltotetraose from bamboo stem extract (BSE) in mouse vascular smooth muscle cells.[Pubmed: 27067145]
Expression of intercellular adhesion molecule-1 (ICAM-1) on vascular smooth muscle cells (VSMCs) plays an important role in the progression of atherosclerosis. We investigated the effects of bamboo stem extract (BSE) on motility and ICAM-1 expression by using mouse MOVAS-1 cells. Active constituents of BSE exhibiting an inhibitory activity on TNF-α-induced ICAM1 expression were identified using HPLC.
METHODS AND RESULTS:
The effects of BSE on platelet-derived growth factor (PDGF)-BB-induced migration, tumor necrosis factor alpha (TNF-α)-induced expression of ICAM-1, and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activation were investigated. BSE inhibited migration of MOVAS-1 cells and sprout formation by mouse aorta explants. Reverse transcription PCR analysis and promoter reporter assays revealed that BSE suppressed ICAM-1 expression by inhibiting NF-κB activity. In addition, BSE reduced adhesion between VSMCs and monocytes. Several oligosaccharides were identified in BSE. Among the oligosaccharides contained in BSE, Maltotetraose and stachyose were potent inhibitors of TNF-α-induced ICAM-1 expression. We confirmed that Maltotetraose reduced PDGF-induced sprout formation by mouse aorta explants and inhibited TNF-α-induced NF-κB activation and ICAM-1 expression in MOVAS-1 cells.
CONCLUSIONS:
The BSE constituent Maltotetraose may be beneficial in the suppression of early atherosclerosis development and could be developed as a dietary supplement for cardiovascular health.
