    • A humanized antibody against a surface antigen pre-S1 of Hepatitis B virus(HBV) is provided to secure the antigen binding capacity similar to that of a mouse monoclonal antibody and have significantly decreased immunity inducing capacity in human due to having more humanized amino acid residue, thereby being usefully used for preventing and treating HBV infection. A humanized antibody against a surface antigen pre-S1 of HBV is characterized in that an amino acid sequence of a heavy chain region is described as SEQ ID : NO. 10 or an amino acid sequence of a light chain region is described as SEQ ID : NO. 20. An expression vector comprises a gene coding an amino acid sequence described as SEQ ID : NO. 19, a gene coding an amino acid sequence described as SEQ ID : NO. 20, and a chimera antibody coding an invariable region of a human IgG antibody. A composition for preventing and treating Hepatitis B comprises a chimera antibody expressed by the expression vector. A kit for detecting HBV comprises the antibody.
    • 提供针对乙型肝炎病毒(HBV)前S1的抗原表面抗原的人源化抗体以确保与小鼠单克隆抗体相似的抗原结合能力,并且由于具有更多的人源化氨基酸残基而在人体中具有显着降低的免疫诱导能力 从而有效地用于预防和治疗HBV感染。 针对HBV表面抗原pre-S1的人源化抗体的特征在于重链区的氨基酸序列描述为SEQ ID NO: 10或轻链区域的氨基酸序列描述为SEQ ID NO: 表达载体包含编码SEQ ID NO:1所示的氨基酸序列的基因。 19,编码如SEQ ID NO:1所示的氨基酸序列的基因。 20和编码人IgG抗体的不变区的嵌合体抗体。 用于预防和治疗乙型肝炎的组合物包含由表达载体表达的嵌合体抗体。 用于检测HBV的试剂盒包含抗体。

    • PURPOSE: An antibody which specifically binds to TIMP-1 with N-linked beta(1,6) branch or antigen-binding fragment thereof are provided to obtain information of metastasis or progression of cancer. CONSTITUTION: An antibody or epitope fragment thereof specifically binds to TIMP-1(tissue inhibitor of metalloproteinase-1) with N-linked beta(1,6) branch. The antibody and antigen-binding fragment thereof also specifically binds to TIMP-1 further comprising sialic acid at the end of N-linked beta(1,6) branch sugar chain. A method for preparing the antibody or antigen-binding fragment thereof comprises: a step of culturing host cells which is transformed by a recombinant vector; and a step of expressing the antibody and antigen-binding fragment thereof in the host cells. A composition for diagnosing cancer metastasis or progression contains the antibody or antigen-binding fragment thereof as an active ingredient.
    • 目的:提供与N-连接的β(1,6)支链或其抗原结合片段特异性结合TIMP-1的抗体,以获得癌症转移或进展的信息。 构成:抗体或其表位片段与N-连接的β(1,6)分支特异性结合TIMP-1(金属蛋白酶-1的组织抑制剂)。 抗体及其抗原结合片段还特异性结合在N-连接的β(1,6)分支糖链末端进一步包含唾液酸的TIMP-1。 制备抗体或其抗原结合片段的方法包括:培养由重组载体转化的宿主细胞的步骤; 以及在宿主细胞中表达抗体及其抗原结合片段的步骤。 用于诊断癌症转移或进展的组合物含有作为活性成分的抗体或其抗原结合片段。
