    • Gene diagnosis to determine the objective DNA is disclosed, which is performed by preparing single-stranded gene (3) from a sample, making the single-stranded gene (3) to react with RNA gene probe (4) which specifically reacts with the objective DNA in order to form DNA-RNA hybrid (5), making the DNA-RNA hybrid (5) to react with liposome agent (6) for gene detection, where the liposome agent (6) has a part of monoclonal antibody or RNase H immobilized on the surface of the liposome which is formed of a phospholipid and which contains a fluorescent material as a marker material therein, making a composite of the DNA-RNA hybrid and the liposome agent to react with anti-nucleic acid antibody (7) and complement (8), and breaking the liposome agent (6) to detect the marker material flowed out.
    • 公开了确定目标DNA的基因诊断,其通过从样品中制备单链基因(3)进行,使得单链基因(3)与特异性与目标反应的RNA基因探针(4)反应 DNA,以形成DNA-RNA杂交体(5),使DNA-RNA杂交体(5)与脂质体试剂(6)反应进行基因检测,其中脂质体试剂(6)具有单克隆抗体或RNA酶H 固定在由磷脂形成并且含有荧光材料作为标记材料的脂质体的表面上,使DNA-RNA杂交体和脂质体试剂的复合物与抗核酸抗体(7)和 补体(8),并破坏脂质体试剂(6)以检测流出的标记物质。
