General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Toward the automated synthesis of carbohydrates and glycosaminoglycans.[Reference: WebLink]

Glycosaminoglycans are crucial components of the extracellular matrix and cell surface and access to define sequences is required to fully appreciate their role in biology. As is the case with most complex polysaccharides, the chemical synthesis of glycosaminoglycan structures is challenging.
METHODS AND RESULTS:
This thesis describes efforts towards the construction of oligosaccharides with the ultimate goal of the automated synthesis of glycosaminoglycans. The use of glycosyl phosphates of glucosamine and glucuronic acid as competent glycosylating agents is illustrated. Further expansion of the glycosyl phosphates methodology to the construction of C-aryl and C-alkyl glycosides and resulted in the synthesis of the natural product 8,1 0-Di-O-methylbergenin. The automated solid-phase synthesis of two complex oligosaccharides is described. The complex-type high mannose trisaccharide and the proteoglycan linkage region tetrasaccharide were synthesized in a fully automated fashion. The efforts towards the synthesis of two glycosaminoglycans - hyaluronic acid and chondroitin sulfate - are discussed.
CONCLUSIONS:
The work focuses on the discovery of a glycosylating agent suitable for the automated solid-phase synthesis. The synthesis of glucuronic acid from glucose is described using an oxidation procedure not previously explored in oligosaccharide construction.

Short total synthesis of 8,10-di-O-methylbergenin.[Pubmed:12182600]

Org Lett. 2002 Aug 22;4(17):2965-7.

[reaction: see text] A short, high-yielding synthesis of the C-glucoside 8,10-Di-O-methylbergenin is reported. Key elements of the synthesis are a stereoselective installation of a beta-C-aryl linkage, a palladium(0)-catalyzed aryl carbonylation, and a regioselective lactonization reaction. This pathway should allow access to a host of bergenin analogues.
