    • In the case when there are two objective biological activities, and the aim is to isolate a compound having at least one biological activity, the present inventors developed an assay method wherein a common detection marker is utilized for separately detecting the presence or absence of each of the biological activities. The present inventors discovered that a compound having at least one of two or more distinct biological activities can be efficiently and conveniently detected by simultaneously assaying at least one test sample or more by the above-mentioned method. Furthermore, for a test sample that proved to be positive by the detection method, they found that it is possible to efficiently and conveniently screen for a test sample having an objective specific biological activity by combining with a method wherein an individual activity of a test sample can be detected to specify the biological activity.
    • 在存在两个目标生物活性的情况下,目的是分离具有至少一种生物活性的化合物时,本发明人开发了一种测定方法,其中使用常见的检测标记来分别检测每种化合物的存在或不存在 生物活动。 本发明人发现通过上述方法同时测定至少一种测试样品,可有效地方便地检测具有两种或更多种不同生物活性中至少一种的化合物。 此外,对于通过检测方法证实为阳性的测试样品,他们发现可以通过结合其中测试样品的单独活性的方法有效和方便地筛选具有客观特异性生物活性的测试样品 可以检测到指定生物活性。

    • A humanized antibody against tissue factor (TF), comprising:A: a humanized H chain comprising (1) a H chain V region comprising the H chain CDRs of a mouse monoclonal antibody against TF and the H chain FRs of a human antibody, and (2) the H chain C region of a human antibody; andB: a humanized L chain comprising (1) an L chain V region comprising the L chain CDRs of a mouse monoclonal antibody against TF and the L chain FRs of a human antibody, and (2) the L chain C region of a human antibody.After generating a humanized V region by grafting the CDRs of a mouse monoclonal antibody onto a human antibody, a humanized antibody having a higher activity is searched by replacing the FR of the above region with the corresponding FR of the human antibody having a high homology.
    • 一种抗组织因子(TF)的人源化抗体,包括:A:人源化H链,其包含(1)H链V区,其包含针对TF的小鼠单克隆抗体的H链CDR和人抗体的H链FR,以及 (2)人抗体的H链C区; 和B:人源化L链,其包含(1)包含针对TF的小鼠单克隆抗体的L链CDR和人抗体的L链FR的L链V区,和(2)人的L链C区 抗体。 通过将小鼠单克隆抗体的CDR移植到人抗体上产生人源化V区后,通过用具有高同源性的人抗体的相应FR代替上述区域的FR来搜索具有较高活性的人源化抗体。
