    • The purpose of the present invention is to provide a diabody-type bispecific antibody, which is characterized by having low immunogenicity and high infiltrating activity into tumor tissues, and by being easily mass-produced at a low cost with use of microorganisms, and by being easily altered in function by means of genetic engineering. The diabody-type bispecific antibody shows a more remarkable effect than the conventional diabody-type bispecific antibodies and chemically synthesized bispecific antibodies even in a very low concentration and in the absence of the super antigen. The present invention is related to a diabody-type bispecific antibody, having a first specificity to a human epidermal growth factor (EGF) receptor and a second specificity to a surface antigen expressed by a cell having phagocytosis or cytotoxic activity, a single-chain polypeptide constituting the antibody or each region contained therein, a nucleic acid encoding the polypeptide, a replicable cloning vector or expression vector comprising the nucleic acid, a host cell transformed with the vector, and a pharmaceutical preparation comprising thereof.
    • 本发明的目的是提供一种双抗体型双特异性抗体,其特征在于对肿瘤组织具有低的免疫原性和高的渗透活性,并且通过使用微生物容易地以低成本批量生产,并且通过 通过遗传工程容易地改变功能。 双抗体双特异性抗体比常规的双抗体型双特异性抗体和化学合成的双特异性抗体甚至在非常低的浓度和不存在超抗原的情况下显示出更显着的效果。 本发明涉及对人表皮生长因子(EGF)受体具有第一特异性的双抗体型双特异性抗体和由具有吞噬作用或细胞毒活性的细胞表达的表面抗原的第二特异性,单链多肽 构成抗体或其中包含的每个区域,编码多肽的核酸,可复制的克隆载体或包含该核酸的表达载体,用该载体转化的宿主细胞及其包含的药物制剂。

    • A wave absorber comprising a sintered ferrite tile wave absorber as a base substrate lowermost relative to the incident wave, and one or more laminates comprising two layers as one set, with a dielectric layer as a lower layer and a dielectric loss-causing layer as an upper layer, laminated on the base substrate. The wave absorber of the present invention is thin, but is capable of absorbing waves over wide frequency bands of from tens of megahertz to a dozen or so gigahertz. By making the absorber thin, the absorber weighs less and is easy to handle, which in turn leads to fine workability and low construction cost.
    • 一种波形吸收体,其特征在于,包括作为基底基板的烧结铁氧体磁阻波浪吸收体相对于入射波最低的一个波长吸收体,以及一个或多个层叠体,其包含两层作为一组,其中介电层为下层,介电损耗层为 上层,层压在基底上。 本发明的吸波体较薄,但能够在数十兆赫兹到十几千兆赫兹的宽频带上吸收波。 通过使吸收体变薄,吸收体重量少,易于处理,反而导致加工性能好,施工成本低。
