摘要:
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.

摘要:
The present invention provides an antibody which has the following features, its active fragment, or a derivative thereof: a) It specifically binds to human platelet membrane glycoprotein VI (GPVI); b) The function to activate a platelet and/or the function to induce a thrombocytopenia in vivo are low; and c) It at least partially depletes GPVI on the platelet membrane by contacting with a platelet.

摘要:
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.
