  • Patent number: 7838667
    Abstract: A method of grafting galactomannan-type polysaccharide polymers, preferably guar, to a functional group by irradiation with high energy electron beams in the presence of an unsaturated monomer-compressing the described functional group. The method may include the depolymerization of the grafted polymer to a pre-selected low molecular weight. The preferred galactomannans for treatment according to this method are guar gum, guar splits and hydroxypropyl guar. In a preferred embodiment the guar gum is also depolymerized, preferably to a molecular weight of below about 700,000 Daltons, and most preferably to a molecular weight of between about 100,000 Daltons to about 250,000 Daltons. The depolymerized guar most preferably has a polydispersity of less than about 3.0 and is useful in oil well fracturing to enhance oil production.

  • Patent number: 7816517
    Abstract: In one embodiment of the present invention, a first test tube including therein a dehydrated sample containing a sugar chain and a labeling agent solution made of 2-aminopyridine/acetic acid are stored in a well-closed container with the first test tube and the labeling agent solution secluded from each other. The labeling agent solution is heated, and the 2-aminopyridine is evaporated so as to be in contact with the sugar chain, thereby obtaining a pyridylamination sugar chain from the sugar chain. As a result, it is possible to provide the saccharide fluorescence labeling apparatus and the saccharide fluorescence labeling method whereby it is possible to simplify and ensure an operation for reacting saccharide into the pyridylamination sugar chain.
