摘要： 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.
摘要翻译：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。

摘要： A structure comprises at least a porous body holding a substance releasably, comprising a capping member for keeping the substance inside the pore and/or on at least a part of the entire surface of the porous body, and a connecting member for connecting the porous body and the capping member separably, the connecting member comprising a biopolymer compound. A method for releasing a substance from the structure set forth comprises the steps of applying stimulation from outside to the structure, and cleaving at least one of the bonding between the connecting member and the capping member and the bonding between the connecting member and the porous member to make the substance releasable from the structure.

摘要： This invention provides a method for measuring an antigen concentration in a sample, which comprises: preparing VH-domain polypeptide and VL-domain polypeptide of an antibody specific to the antigen; labeling one of the polypeptides with a reporter molecule to form labeled polypeptides, and immobilizing the other polypeptides onto solid-phase to form immobilized polypeptides; contacting the antigen-containing sample and the labeled polypeptides with the solid-phase; and measuring the reporter molecule of the labeled polypeptides bound to the immobilized polypeptides. The present invention permits simpler and quicker sandwich ELISA for measurements of an antigen concentration in high sensitivity.
