FIELD: medicine.
SUBSTANCE: invention describes fused partner cells making it possible to produce heterohybridomas of cells of biological species different from a mouse. Heterohybridomas are produced by fused myeloma cells produced from an animal of a first biological species with leukemia cells produced from an animal of a second biological species which have an additional S-phase in a cell cycle and exhibit a diploidisation property. The fusion partner cell SPYMEG is deposited, No. FERM BP-10761 and can be used for hybridoma production. What is described is hybridoma producing antibodies produced by fusion of fusion partner cell and a third cell with antibody-producing ability. The invention describes methods for producing a fusion partner cell, a hybridoma and an antibody-producing cell, and also methods for producing antibodies. Use of the invention provides stable and simple production of the substances with the use of hybridomas in a wide range of species of animals.
EFFECT: hybridomas stably keep a phenotype throughout the whole process of cloning.
