A U.S. Patent for the “Recombinant Production of Mixtures of Antibodies” was awarded to Merus on December 17th, 2019. The present invention are methods for producing mixtures of antibodies from a single host cell clone, wherein, a nucleic acid sequence encoding a light chain and nucleic acid sequences encoding different heavy chains are expressed in a recombinant host cell. The recombinantly produced 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. Learn More
