摘要:
To identify antigens of the 2D7 antibody, the present inventors cloned the 2D7 antigen. The results suggested that the 2D7 antigen is an HLA class I molecule. Based on this finding, the present inventors examined whether the 2D7 antibody has cell death-inducing activity. Nuclei fragmentation was observed when the 2D7 antibody was cross-linked with another antibody, indicating that cell-death was induced. Further, diabodies of the 2D7 antibody were found to have very strong cell death-inducing activities, even without the addition of another antibody. These results indicate that minibodies of an HLA-recognizing antibody can be used as cell death-inducing agents.

An LED with a semiconductor light emitting element that emits a blue or a blue-violet light, and a fluorescent material that absorbs some or all of the light emitted from the element and emits a fluorescent light of a wavelength different from the absorbed light. The fluorescent material is a mixed fluorescent material obtained by mixing a first fluorescent material that emits a blue-green or a green light, a second fluorescent material that has a peak emission wavelength longer than that of the first fluorescent material and emits a green or a yellow-green light, a third fluorescent material that has a 1 peak emission wavelength longer than that of the second fluorescent material and emits a yellow-green, a yellow or a yellow-red light, and a fourth fluorescent material that has a peak emission wavelength longer than that of the third fluorescent material and emits a yellow-red or a red light.

An object of the present invention is to provide novel pharmaceutical compositions using anti-GRP78 antibodies. More particularly, the present invention aims to provide a novel method of cancer treatment using anti-GRP78 antibodies, novel cell growth inhibitors and anticancer agents that contain anti-GRP78 antibodies, as well as novel anti-GRP78 antibodies.The present inventor attempted to prepare antitumor antibodies that would target GRP78 the localization of which in cancer cells changed to the cell membrane and the inventor successfully obtained an anti-GRP78 antibody that would bind specifically to the cell surface of cancer cells; this eventually led to the accomplishment of the above-mentioned objects.
摘要:
The present inventors constructed a DNA expression vector encoding 2D7sc(Fv)2 in which the heavy chain variable region sequence (VH) and the light chain variable region sequence (VL) of the 2D7 antibody is arranged in the order of VH-VL-VH-VL, and these sequences are linked by a 15-mer linker. The vector was introduced into CHO cells and a 2D7sc(Fv)2-producing expression cell line was established. When 2D7sc(Fv)2 was expressed in this cell line, purified, and cell death-inducing experiments performed, 2D7sc(Fv)2 was found to have a concentration-dependent cell death-inducing activity.
摘要:
CD22 diabodies, in which heavy-chain and light-chain variable regions are linked by a 5-mer linker, were produced based on known sequence information for two types of anti-CD22 antibodies. The two diabodies produced were analyzed for their activity of binding to lymphoma cells and inducing lymphoma cell death (apoptosis). As a result, both diabodies were revealed to bind to the B-lymphoma cell line, “Raji”, and to have apoptosis-inducing activity towards Raji cells as well as towards another B-lymphoma cell line: Daudi cells. These results show that minibodies of antibodies that recognize CD22 can be used as apoptosis-inducing agents for tumor cells such as lymphoma cells.
