  • Publication number: 20120309034
    Abstract: A reaginic antibody of Ku86 and a substance capable of binding with the autoantibody of Ku86 are acted on a complex of Ku86 and the autoantibody thereof in a subject. Said complex can be measured by measuring the obtained immune complex of the aforementioned complex, reaginic antibody, and substance capable of binding with the autoantibody of Ku86. As a consequence, it is possible to determine whether the cancer is a primary hepatoma, colon cancer, stomach cancer, pancreatic cancer, breast cancer, lung cancer, or an esophageal cancer.

  • Publication number: 20110239313
    Abstract: Silkworms which have (i) a DNA encoding a transcriptional regulator operably linked downstream of a promoter of a DNA encoding a protein specifically expressed in the silk gland and (ii) a DNA encoding TRACP5 operably linked downstream of a target promoter of the transcriptional regulator were produced. The result showed that active TRACP5b was produced from the silkworms. This means that TRACP5 produced from the silk gland of the silkworms undergoes processing in the silk gland that is similar to the processing taking place at bone resorption sites.

  • Publication number: 20100248393
    Abstract: For determining an antigen or an antibody against the antigen in a sample, a determination reagent is used which comprises an antibody capable of causing an antigen-antibody reaction with the antigen contained in the sample and an antigen capable of causing an antigen-antibody reaction with both of the antibody contained in the sample and the antibody contained in the reagent. Either one of the antigen and the antibody in the reagent is supported on a microparticle. The sample is mixed with the reagent. The antigen or the antibody in the sample can be determined based on the degree of increase or decrease in agglutination caused by the antigen-antibody reaction. It becomes possible to determine both of an antigen and an antibody against the antigen in a sample accurately using one and the same reagent.
