Provided are a humanized monoclonal antibody against PcrV or a part thereof, and a pharmaceutical composition containing the same as an active ingredient, as an effective means for therapy of infection, particularly infection with. Concretely, the humanized monoclonal antibody of the present invention has an excellent inhibitory activity on the cytotoxicity with respect to a target cell of. Also, the humanized monoclonal antibody of the present invention has a high affinity for PcrV.

An objective of the present invention is to provide a MUC1 antibody having high specificity to cancer cells. The objective has been achieved by the present inventors who found that a cancer-specific sugar chain can be specifically recognized in MUC1 and a cancer cell expressing MUC1 having such a cancer cell specific sugar chain can be recognized. The present invention provides an antibody, an antigen-binding fragment thereof or a MUC1-binding molecule, having, for example, 40-fold specificity or more for a cancer-associated structure of MUC1 as compared to that of a normal tissue-associated structure of MUC1.

MUC1 antibody

An object of the present invention is to provide an antibody which does not bind to a normal cell, and is specific for a cancer cell. The object was solved by the finding by the present inventors that an antibody obtained by immunizing an animal using a 2,3ST glycopeptide as an antigen unexpectedly recognizes a sugar chain specific for a cancer specifically and remarkably, and consequently, can recognize and kill a cancer cell expressing MUC1 having such a cancer cell-specific sugar chain. The present invention provides, for example, an antibody, an antigen-binding fragment thereof or a MUC1-binding molecule, in which specificity for a cancer-associated structure of MUC1 is 100-fold or more as compared with that for a normal tissue-associated structure of MUC1.

A neutralizing monoclonal antibody specifically reacting with MMP13, a method of neutralizing enzyme activity of MMP13 and an immunological measuring method each using the antibody, as well as a diagnostic agent and a pharmaceutical composition containing the antibody, are provided. Various antibodies to MMP13 have been hitherto obtained, but an antibody having neutralizing activity against MMP13 has not been obtained. The present inventors intensively studied, as a result, found out a neutralizing antibody having specificity for MMP13, resulting in completion of the present invention.

CD30 is a receptor expressed on cells of Hodgkin's disease and certain leukemias. The extracellular portion of CD30 is cleaved, releasing a form known as sCD30. The invention relates in part to the discovery that a residual, extracellular 'stalk' of CD30 remains after cleavage of sCD30. The stalk provides an advantageous and previously unrecognized target for immunotoxins. The invention provides antibodies that bind to the CD30 stalk or to epitopes destroyed upon the cleavage of CD30 which results in the stalk. The invention further provides new anti-CD30 antibodies that form effective immunotoxins and are particularly suitable for making disulfide stabilized Fv ('dsFv')-immunoconjugates. The dsFv immunoconjugates can be used as reagents to label CD30-expressing cancer cells or to inhibit the growth of CD30-expressing cancer cells. Moreover, the invention provides anti-CD30 antibodies that activate complement-dependent cytotoxicity.

The present invention relates to a sandwich immunoassay for rapidly and readily measuring N-peptide using two kinds of monoclonal antibodies recognizing different portions of the N-peptide. The method for measuring N-peptide or a precursor thereof includes the steps of: incubating a mixture containing a sample and a first monoclonal antibody recognizing a portion of N-peptide; adding a labelled second monoclonal antibody recognizing a portion of N-peptide to the mixture, followed by further incubation; and detecting the resulting antigen-antibody complex in the mixture. Alternatively, the method includes the steps of: incubating a mixture containing a sample, a first monoclonal antibody recognizing a portion of N-peptide, and a labelled second monoclonal antibody recognizing another portion of N-peptide; and detecting the resulting antigen-antibody complex.

The present invention relates to a process of preparing a sandwich immunoassay of NAG, which comprises (1) reacting NAG with an immobilized anti-NAG monoclonal antibody and a labeled anti-NAG monoclonal antibody to form a complex of immobilized antibody-NAG-labeled antibody and (2) detecting the activity of said reacted and unreacted labeled anti-NAG antibody. This sandwich immunoassay is useful for diagnosis of renal disease, hepatitis, leukemia, and other such diseases. It also allows the direct and specific detection of NAG isozymes B and I in urine and blood.
