    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.

    摘要: A reshaped human anti-HM1.24 antibody comprising: (A) L chains each comprising (1) a constant region of a human L chain, and (2) FRs of a human L chain, and CDRs of L chain of mouse anti-HM1.24 monoclonal antibody; and (B) H chains each comprising (2) a constant region of a human H chain, and (2) FRs of a human H chain, and CDRs of H chain of mouse anti-HM1.24 monoclonal antibody. Since the majority of the reshaped human antibody is derived from human antibody and the CDR has a low antigenicity, the reshaped human antibody of the present invention has low antigenicity and therefore is very promising in medical and therapeutic applications.
