Abstract: The invention provides antibodies against a non-muscular myosin heavy chain type A or a mutant thereof, and F(ab?)2 fragments thereof, as well as a method of treating cancer with such antibodies and F(ab?)2 fragments thereof.

Abstract: 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.

Abstract: Provided is a remedy for cancer which remedy is specific to cancer tissue and has therapeutic effects on mammary cancer. The remedy is available by associating an antitumor substance with a human monoclonal antibody having amino acid sequences of SEQ. ID. NOS. 1, 2 and 3 of Sequence Listing in hypervariable regions of a heavy chain and amino acid sequences of SEQ. ID. NOS. 4, 5 and 6 of Sequence Listing in hypervariable regions of a light chain by attaching the antibody to a liposome having the antitumor substance encapsulated therein.

Abstract: 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.

Abstract: A liposome wherein a compound containing a polyalkylene glycol moiety is bonded through a thioether group and an antibody is bonded through a thioether group to a liposome comprising lipids whose partial component has maleimidated terminal, wherein an amount of the bonded compound and an amount of bonded antibody is 15 to 50 mole % and 0.1 to 2 mole %, respectively, based on one mole of the maleimidated lipid contained in the liposome. The liposome achieves both excellent blood retention and therapeutic effect.

Abstract: A method for preparing a closed vesicle by a rehydration of a closed vesicle using a rehydration solution, wherein said closed vesicle comprises a dehydrated micelle particle or dehydrated amphipathic micelle bilayers, preferably a liposome loading a pharmaceutically active substance, and the method is characterized in that the rehydration is carried out at a low temperature such as in the range of from 0° C. to 10° C. The method can provides a rehydrated stable vesicle without a leak of the loaded substance.

Abstract: Provided is a diagnostic comprising a peptide or protein capable of recognizing at least a portion of a tissue section and a fluorescent substance having the below-described characteristics: i) having, in a predetermined excitation wavelength, an emission wavelength not adjacent to a wavelength region of nonspecific autofluorescence which the tissue section has; and ii) permitting simultaneous observation of the image of the peptide or protein and the image of the tissue section. A diagnostic method and diagnostic kit each of which uses the peptide or protein, and the fluorescent substance is provided. A therapeutic agent administered to a disease after selection of the appropriate agent for the disease by using the above-described method. Also, a tissue section stained by the peptide or protein and the fluorescent substance is provided. In addition, a method of analyzing expression and/or behavior of a protein by using the fluorescent substance is provided.

Abstract: A human monoclonal antibody specifically binding to a surface antigen of cancer cell membrane, an isolated DNA encoding the antibody, and a hybridoma producing the antibody.
