摘要:
An antibody library is prepared by selecting a light chain variable region capable of binding to the variable region of heavy chain to reproduce an active conformation and using the same. Because of being capable of maintaining the diversity of the heavy chain variable region at a high ratio in vitro, the antibody library of the present invention is expected as enabling the acquisition of antibodies with various binding activities.
摘要:
The present invention provides camel antibody libraries that maintain in vivo diversity of camelid antibody variable region genes. The in vivo diversity of antibody variable region genes can be accomplished by, for example, mixing genes derived from a plurality of animals or modifying gene amplification conditions. Conventional methods yield only VHHs with limited repertoire diversity. However, the present invention provides libraries comprising genes encoding functional VHHs with sufficient repertoire size. According to the present invention, libraries that enable to freely obtain VHHs against arbitrary antigens are provided. VHHs have excellent solubility and stability, and show a reactivity that usually cannot be expected from tetrameric IgGs.

摘要:
It is intended to clarify a molecule which is available as a target in treating or diagnosing cancer and utilize the molecule in the medical field or the research field. By treating IgSF4, which has been identified as a molecule specifically expressed in lung cancer cells, with an antibody, and ADCC activity is exerted. Based on this finding, an anti-IgSF4 antibody is provided as a means efficacious in treating cancer, etc.

摘要:
It is intended to provide a method whereby a plural number of antibodies against cell surface antigens are quickly classified and to provide a method whereby antigens of the thus classified antibodies are quickly identified. Further, it is intended to provide a method of promoting the utilization of the useful data obtained by the above methods. Furthermore, it is intended to provide an antibody which is effective in treating or diagnosing cancer. Namely, a method of classifying antibodies which comprises: (1) the step of preparing a plural number of antibodies respectively recognizing cell surface antigens; (2) the step of bringing each of these antibodies into contact with a cell of the same species; (3) the step of analyzing each of the cells having been treated in the step (2) by flow cytometry and thus obtaining data indicating the reactivity of each antibody with its cell surface antigen; and (4) the step of comparing the thus obtained data and classifying the individual antibodies depending on the similarity. A method of identifying antigens which further comprises: (5) the step of selecting one to several antibodies from each antibody group formed in the step (4) and identifying antigens thereof; and (6) on the assumption that antigens of the antibodies belonging to a single antibody group are the same or highly related to one another, making relations between the antigens having been identified in the step (5) and the antibody groups to thereby identify the antigens. An antibody against HER1, an antibody against HER2, an antibody against CD46, an antibody against ITGA3, an antibody against ICAM1, an antibody against ALCAM, an antibody against CD147, an antibody against C1qR, an antibody against CD44, an antibody against CD73, an antibody against EpCAM and an antibody against HGFR, each obtained by using the above methods.

摘要:
A process for producing a hermetic electric compressor for a refrigerating or air-conditioning apparatus using a refrigerant having a hydrofluorocarbon base which comprises a motor unit, a compressing unit driven by the motor unit and a sealed housing enclosing the motor unit and the compressing unit and stores a refrigeration oil on the bottom of the sealed housing, wherein a solventless varnish comprising a thermosetting resin having at least two (meth)acryloyl groups in one molecule, a low-viscosity vinyl or 1-alkylvinyl monomer having an ether or ester linkage as a reactive diluent and an organic peroxide as a reaction initiator is used as an insulating varnish to insulate and fix the magnet wires of the stator of the motor unit, and the solventless varnish is cured by heating at a temperature of from 153 to 180.degree. C. for from 0.5 to 3.5 hours.
摘要:
A refrigerant circulating system that uses a highly polar refrigerant, as typified by a hydrofluorocarbon-based one, and a refrigerating oil that has slight solubility with a liquid refrigerant on the condensation side. Also, a refrigerant circulating cycle that uses a highly polar refrigerant, as typified by a hydrofluorocarbon-based one, and a refrigerating oil that has a slight solubility with a liquid refrigerant and which has a greater specific gravity than the liquid refrigerant. Thereby, it provides a high electrical insulation and moisture resistance, good oil return to the compressor, and high reliability.
