Abstract

NEW MATERIAL:A monoclonal antibody capable of recognizing a glycolipid derivative expressed by the formula. USE:A detecting reagent for cancer-related saccharide chain antigens and treating agent for cancer. PREPARATION:For example, the glycolipid derivative expressed by the formula is adsorbed in an emulsion of monophosphoryl-lipid A and dimycolic acid trehalose and repeatedly administered into the abdominal cavity of BALB/c mouse for immunization. After the final immunization, splenic cells are recovered and then fused to mouse myelomatous cells using polyethylene glycol, etc., and a clone capable of producing an antibody specifically binding to the glycolipid derivative expressed by the formula is selected from the produced hybridoma according to the Kohler method, etc., and cloned by a limiting dilution method, etc., to provide a cloned hybridoma. The resultant hybridoma is subsequently cultured to afford the objective monoclonal antibody capable of recognizing the glycolipid derivative expressed by the formula.

[Prior Art] It is known that sugar chains of glycosphingolipids exist on cell surfaces as antigen-determining sites associated with cancer. That is, it has been reported that when cells become cancerous, glycolipid sugar chains change, and glycolipids that are not found in normal cells are detected on the surface of cancer cells.

[Problems to be Solved by the Invention] It is known that sugar chains of glycoproteins, like glycolipids, cause cancerous changes when cells become cancerous. In particular, mucin-type glycoproteins are known to be secreted into serum and are very useful as cancer-related antigens. However, when monoclonal antibodies are prepared using mucin-type glycoprotein as an antigen, antibodies related to protein portions are obtained, and antibodies related to sugar chains are difficult to obtain. Therefore, we developed a compound that can serve as an antigen to obtain antibodies against mucin-type glycoprotein sugar chains.
Creating monoclonal antibodies is an important technical challenge.
