The invention provides 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...http://www.google.es/patents/US7927834?utm_source=gb-gplus-sharePatente US7927834 - Recombinant production of mixtures of antibodies
