Hybridoma-producing NSO myeloma cell line

摘要

This invention relates to an NSO myeloma cell line which has increased fusion frequency, and to a method of producing said cell line. The NSO cell line of the invention, when fused with B cells, produces monoclonal antibody-secreting hybridoma which has increased resistance to death. In addition, the monoclonal antibodies secreted by said hybridomas have increased affinity for foreign antigens and for autoantigens.
