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 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 the recombinantly produced antibodies are also provided by the invention. Such mixtures can be used in a variety of fields.

Recombinant production of mixtures of antibodies

Described are methods for identifying, selecting, and obtaining mammalian cells capable of producing proteinaceous molecules having predetermined post-translational modifications, wherein the post-translational modifications are brought about by the mammalian cell in which the proteinaceous molecule is expressed. Preferably, the predetermined post-translational modifications include glycosylation. Also described are methods for obtaining and producing proteinaceous molecules, using mammalian cells obtainable by a method of the present invention. Preferably, the proteinaceous molecules include erythropoietin (EPO), since EPO's effect depends heavily on its glycosylation pattern. Mammalian cells that have been obtained on the basis of their ability to produce proteins and/or post-translational modifications that are indicative for a predetermined post-translational modification that is desired are also provided. Preferably, the mammalian cells have neural characteristics and properties such that significant amounts of recombinant proteins can be produced that harbor 'neural- or brain-type' properties.
