  • Patent number: 9683006
    Abstract: The present invention provides substance which can specifically interact with sugar chains. Further, the present invention provides a method for separating, concentrating, or purifying sugar chains or a sugar chain-containing substance in a sample, comprising the steps of: a) contacting a sugar chain-trapping carrier comprising a substance which can specifically interact with sugar chains with the sample in a fluid phase under conditions that the sugar chain-trapping carrier can react with the sugar chains or sugar chain-containing substance; b) isolating a composite of the sugar chain-trapping carrier and the sugar chains or sugar chain-containing substance from the fluid phase; and c) exposing the composite to the conditions that the interaction between the sugar chain-trapping carrier and the sugar chains or sugar chain-containing substance is at least partially eliminated.

  • Patent number: 9447316
    Abstract: Provided is a hollow particle aggregate formed by aggregating a plurality of self-organizable particles, wherein a metal core is modified by a surface modifier for a metal core comprising a first segment comprising an optionally branched fluorinated alkylene glycol group, an optionally branched fluorinated alkylene group, or an optionally branched fluorinated azaalkylene group; a second segment comprising at least one hydrophilic group and bonding to one of the ends of a main chain of the first segment; and a functional group that bonds directly or indirectly to the another end of the main chain of the first segment and is able to bond to the metal core.

  • Patent number: 9139607
    Abstract: The present invention provides substance which can specifically interact with sugar chains. Further, the present invention provides a method for separating, concentrating, or purifying sugar chains or a sugar chain-containing substance in a sample, comprising the steps of: a) contacting a sugar chain-trapping carrier comprising a substance which can specifically interact with sugar chains with the sample in a fluid phase under conditions that the sugar chain-trapping carrier can react with the sugar chains or sugar chain-containing substance; b) isolating a composite of the sugar chain-trapping carrier and the sugar chains or sugar chain-containing substance from the fluid phase; and c) exposing the composite to the conditions that the interaction between the sugar chain-trapping carrier and the sugar chains or sugar chain-containing substance is at least partially eliminated.
