Recombinant production of mixtures of antibodies

摘要

The invention provides methods for producing mixtures of antibodies from a single host cell clone. Thereto a nucleic acid sequence encoding a light chain, and nucleic acid 10 sequences encoding different heavy chains are expressed in a recombinant host cell. The antibodies in the mixtures according to the invention suitably comprise identical light chains paired to different heavy chains capable of pairing to the light chain, thereby forming functional antigen binding domains. Mixtures of antibodies are also provided by the invention. Such mixtures can be used in a variety of fields.
