    • The purpose of the present invention is to provide an agglutination enhancer which shows superior agglutination enhancing effect to those of conventional immunoagglutination enhancers, and the present invention relates to an agglutination enhancer for an immunoagglutination measurement method which comprises a polymer having a monomer unit shown by the following general formula [1]: (Wherein R1 represents a hydrogen atom or a methyl group; R2 and R3 independently represent a methyl group or an ethyl group, respectively; X represents —NH— or an oxygen atom; n represents an integer of 1 to 6; and m represents an integer of 1 to 3), and an immunoagglutination measurement method in which, in the coexistence of the above-described agglutination enhancer for immunoagglutination measurement method, an antibody against analyte or an antigen for the analyte is brought into contact with the analyte to cause an antigen-antibody reaction.

    • A method for the preparation of a novel recombinant DNA, which comprises (1) cleaving with an endonuclease a temperate phage DNA having an endonuclease-sensitive region not in the DNA segment participating in the replication of phage DNA and the integration of phage DNA into a host chromosome but at least in the DNA segment carrying genetic information for the coat protein production and another DNA carrying intended genetic information, (2) adding DNA-ligase to the mixture of both cleft DNA's, and (3) recovering from the mixture a phage DNA having its coat protein producing ability deleted by the replacement of the DNA segments carrying genetic information for the coat protein production with a DNA fragment carrying the intended information.
    • 一种制备新的重组DNA的方法,其包括(1)用核酸内切酶切割温和的噬菌体DNA,所述温带噬菌体DNA具有参与噬菌体DNA复制的DNA片段中不具有内切核酸酶敏感区域,并将噬菌体DNA整合到 宿主染色体,但至少在DNA片段中携带外壳蛋白生产的遗传信息和携带预期遗传信息的另一个DNA,(2)向裂解DNA的混合物中加入DNA连接酶,和(3)从混合物中回收噬菌体 通过用携带预期信息的DNA片段替代携带用于外壳蛋白生产的遗传信息的DNA片段,缺失其外壳蛋白产生能力的DNA。
