  • Patent number: 8828732
    Abstract: The method of labeling a sugar chain from a biological sample employs a single reaction vessel for the sequential performance of the following steps of (a) isolating a sugar chain from a sample using a sugar-trapping substance; (b) washing the sugar-trapping substance having the sugar chains trapped thereon; (c) releasing the sugar chain from the sugar-trapping substance; and (d) labeling the released sugar chain with UV/visible or fluorescent compound having an amino group forming a stable labeled sugar in fewer steps than a conventional ion exchange based technique.

  • Patent number: 7964410
    Abstract: A method for preparing an analysis sample which involves the sugar chain capture step comprising a reaction of capturing a sugar chain and/or a sugar derivative from a biological sample by using a sugar chain capture agent and the excision step comprising excising a compound containing a moiety capturing the sugar chain and/or the sugar derivative from the sugar chain capture agent after the completion of the sugar chain capture reaction and releasing the compound.

  • Publication number: 20110046364
    Abstract: The present invention relates to a method of labeling a sugar chain, used for labeling a sugar chain contained in a biological sample, aimed at simplifying a process of isolating a sugar chain from a biological sample and labeling it, which includes (a) trapping a sugar chain in a sugar-trapping substance, which is a substance for specifically trapping a sugar chain from a biological sample; (b) washing the sugar-trapping substance having the sugar chains trapped thereon; (c) releasing the sugar chain from the sugar-trapping substance; and (d) labeling the released sugar chain, wherein the processes (a), (b), (c) and (d) are conducted sequentially in a single reaction vessel.

  • Publication number: 20070219309
    Abstract: The object of the invention is to provide an optical material serving as a glass substitute, showing high light transmissivity in a broad wavelength range and capable of being adequately used in producing transparent sheets, optical lenses, liquid crystal display element plastic substrates, color filter substrates, organic EL display element plastic substrates, solar cell substrates, touch panels, optical elements, optical waveguides and LED sealants, among others, by using ordinary glass fillers. The above optical material can be obtained from a transparent composite composition which comprises a transparent resin and a glass filler and in which the transparent resin has an Abbe number of not smaller than 45.

  • Patent number: 7250209
    Abstract: A transparent composite composition is provided which is low in coefficient of linear expansion and excellent in transparency, heat resistance and solvent resistance and can serve as an optical sheet for a liquid crystal display device or organic EL display device, for instance and can thus serve as a glass substitute. The transparent composite composition has a transparent resin (a) and a glass filler (b), and the transparent resin (a) is a copolymer obtained from at least one reactive monomer lower in refractive index than the glass filler (b) and at least one reactive monomer higher in refractive index than the glass filler (b).
