Abstract
A novel cell line for use as a parent for hybridoma preparation is provided. This cell line is derived from tumor cells, in particular human tumor cells, other than those originating from bone marrow cells. A method for establishing this cell line is also provided. By fusing this cell line with cells producing useful physiologically active substances, such as B cells immunized with an antigen, a hybridoma capable of active growth can be prepared. This hybridoma can be cultivated for the production of useful physiologically active substances.
