  • Patent number: 9052320
    Abstract: An object of the present invention is to enable to accurately quantify HBs antigen in the samples for which measured values are low or false-negative results by the conventional assaying method of HBs antigen. In the method of assaying HBs antigen according to the present invention, at least one inner capture probe that binds to a first inner region peptide consisting of 26th to 80th amino acid residues of HBs antigen and at least one outer capture probe that binds to a second outer region peptide consisting of 98th to 156th amino acid residues of HBs antigen are used as capture probes; and at least one inner detection probe which binds to the first inner region and at least one outer detection probe which binds to the second outer region are used as detection probes.

  • Patent number: 8105799
    Abstract: Revealed are that the actions of inflammatory cytokine and the production of inflammatory cytokines such as IL-1 and TNF induced by an inflammatory stimulus as well as the production of other inflammatory cytokines such as IL-6 induced by the former class of inflammatory cytokines are all suppressed by inhibiting the signal transduction through TAK1.

  • Patent number: 6989244
    Abstract: The present invention relates to methods of screening for compounds that inhibit signal transduction by inflammatory cytokines. The methods include providing a sample that contains a TAK1 and a TAB1; contacting the sample with a compound; detecting binding between the TAK1 and the TAB1; and selecting the compound if binding between the TAK1 and TAB1 is inhibited in the sample compared to a control.
