    • The present invention provides an antibody which specifically recognizes an epitope containing a part of a domain based on a finding that the domain ranging from the 269- to 315-positions of human CD14 represented by SEQ ID NO:1 is a site capable of interacting with another protein, an antibodies provided. This antibody can inhibit the interaction between human CD14 and another protein and thus suppress cell activation. And also, the present invention provides hybridomas producing the above antibody or its fragment; a peptide containing the amino acids in the domain as specified above; a method of constructing an antibody with the use of this peptide as an immunogen; and a method of screening a medicament for sepsis involving the step of bringing a test substance into contact with CD14 and TLR.
    • 本发明提供了一种抗体,其特异性识别含有部分结构域的表位,基于以下发现:由SEQ ID NO:1表示的人CD14的269位至315位的结构域是能够与 另一种蛋白质,提供抗体。 该抗体可抑制人CD14与另一种蛋白质之间的相互作用,从而抑制细胞活化。 而且,本发明提供了产生上述抗体或其片段的杂交瘤; 含有如上所述的结构域中的氨基酸的肽; 使用该肽作为免疫原构建抗体的方法; 以及筛选涉及使测试物质与CD14和TLR接触的步骤的败血症药物的方法。

    • The present invention provides an antibody prepared using a peptide as an antigen, the peptide having 8 to 30 amino acid residues selected from an amino acid sequence at positions 1 to 68 of human high-molecular-weight CD14, or an antibody that binds to a peptide having a specific amino acid sequence at a position among the positions 1 to 68. An assay kit for human low-molecular-weight CD14 using the antibody and an assay method of the present invention, preferably a sandwich method, are able to quantitatively or qualitatively determine human low-molecular-weight CD14 with high sensitivity and specificity in a simple manner, so that they are useful for the diagnosis of a patient suffering from sepsis.
    • 本发明提供使用肽作为抗原制备的抗体,所述肽具有选自人高分子量CD14的1至68位的氨基酸序列的8至30个氨基酸残基或结合至 在1至68位的位置具有特定氨基酸序列的肽。使用抗体的人类低分子量CD 14的测定试剂盒和本发明的测定方法,优选夹心法,能够 以简单的方式以高灵敏度和特异性定量或定性地测定人类低分子量CD14,从而可用于诊断患有败血症的患者。
