摘要： Disclosed is a monoclonal antibody which has a heavy chain variable region containing amino acid sequences depicted in SEQ ID NOs:74, 76 and 78 and a light chain variable region containing amino acid sequences depicted in SEQ ID NOs:80, 82 and 84. The monoclonal antibody can be used as a cancer therapeutic agent which acts selectively on a cancer tissue of non-small lung cancer, pancreatic cancer, gastric cancer or the like.

摘要： A novel human monoclonal antibody specifically recognizing cancer cells such as non-small cell lung cancer, pancreatic cancer and gastric cancer cells is produced by hybridomas which are obtained by fusing lymphocytes derived from a cancer tissue of a cancer patient with mouse myeloma cells. An anti-cancer drug is obtained by using the antibody alone or anchoring the antibody on the surface of a liposome containing a toxin or an anti-cancer drug encapsulated therein. More specifically, an anti-cancer drug is obtained by using an antibody, in which variable region of its heavy chain comprises the amino acid sequence of SEQ ID NO: 115 and variable region of the light chain comprises the amino acid sequence of SEQ ID NO: 117, alone or anchoring the antibody on the surface of a liposome containing a toxin or an anti-cancer drug encapsulated therein.
