    • A method for determining telomerase activity using primer extension followed with real time PCR quantification is disclosed. The method of the present invention provides a rapid, sensitive and accurate measurement for telomerase activity in a biological sample. In one embodiment, the method includes the steps of: adding the biological sample to a reaction tube containing a first reaction mixture having a first primer and nucleoside triphosphates, a second reaction mixture having a second primer and a DNA polymerase, and a wax layer that separates the first reaction mixture from the second reaction mixture; incubating the biological sample with the first reaction mixture; admixing the extension product with the second reaction mixture; amplifying and quantifying the extension product using real-time PCR and a control template. In another embodiment, the detection method includes an in situ primer extension step that allows the production of the extension product within an intact cell. In this embodiment, the extension product can be preserved under appropriate conditions for an extended time before the completion of the quantification step.

    • This invention provides a fusion protein (FP4) and the code gene, expression method, and clinical application; its goal is to provide a fusion protein, the code gene, and the expression method as well as to take this fusion protein as the active constituent anti-allergic medicine. In addition, the invention provides the sequence of fusion protein attached on SEQ ID 2 and any derivation protein of the fusion protein (FP4) which includes adding or deleting several amino acids of SEQ ID2 as well as increasing or deducing nuclear tides of SEQ ID 1. We designed to cross-link IgE active receptor and an IgG inhibitory receptor by endogens hinge without any extraneous chemical link. This invention fusion protein has function to block the IgE acceptor, moreover fragment of fusion protein has ability to specifically bind to a native IgG inhibitory receptor containing immunoreceptor tyrosine-based inhibitory motif, thereby inhibiting the IgE-driven mediator release from mast cells and basophils. It will play important role in the allergic disease treatment.
    • 本发明提供融合蛋白(FP4)及其代码基因,表达方法和临床应用; 其目标是提供融合蛋白,代码基因和表达方法,并将该融合蛋白作为活性成分抗过敏药物。 此外,本发明提供了连接在SEQ ID 2上的融合蛋白的序列和融合蛋白(FP4)的任何衍生蛋白,其包括添加或缺失SEQ ID2的几个氨基酸,以及增加或推导出SEQ ID No.1 我们设计通过内源性铰链交联IgE活性受体和IgG抑制受体,而没有任何外来化学连接。 本发明融合蛋白具有阻断IgE受体的功能,此外,融合蛋白的片段具有与含有免疫受体酪氨酸的抑制基序的天然IgG抑制受体特异性结合的能力,从而抑制IgE驱动的介体从肥大细胞和嗜碱性粒细胞释放。 它将在过敏性疾病治疗中发挥重要作用。
