  • Patent number: 7241624
    Abstract: The present invention provides a dendrimer-based biochip, wherein a flow channel through which a solution containing biopolymer molecules is flowed is formed in the substrate of the biochip, a plurality of dendrimer molecules one end of each of which is bound to the walls of the flow channel are formed thereon, and probe biopolymer or antibody molecules are bound to the tips of the dendrimer molecules so that, if the probe biopolymer molecules are bound, then target biopolymer molecules can be captured by means of a complementary combination and, if the antibody molecules are bound, then protein can be extracted by means of antigen-antibody reaction, whereby biopolymers can be retrieved in a highly efficient manner.

  • Publication number: 20060286596
    Abstract: The present invention separates and purifies a negatively charged target biopolymer from among biological samples without involving fluid movements. In other words, a first solution containing said biological samples and a second solution for preserving a separated and purified biopolymer are partitioned by a gel, thereby allowing said target biopolymer to move from within said first solution through said gel into said second solution using electrophoresis or a combination of electrophoresis and magnetophoresis so that said target biopolymer is separated and purified.

  • Publication number: 20050191644
    Abstract: The present invention relates to biopolymer detection methods based on antigen-antibody interactions, wherein the methods show improved S/N ratios, improved detection sensitivities, and reduced detection times. The present invention also relates to application of these methods to biochips. The invention further relates to antibody fixation methods wherein antibody molecules are immobilized to amide group-containing gels, or amide group-containing gels on insoluble substances. Using such gels prevents the nonspecific adsorption of antibody-binding molecules. By embedding these antibody-binding molecules in such gels, their antibody-binding activity is prevented from deteriorating.
