Abstract: The invention relates to a method for manufacturing a recombinant polyclonal protein composition, in particular a recombinant polyclonal antibody composition. The method comprises obtaining a collection of cells transfected with a library of variant nucleic acid sequences, wherein each call in the collection is transfected with and capable of expressing one member of the library, which encodes a distinct member of a polyclonal protein that binds a particular antigen and which is located at the same single site in the genome of individual cells in said collection, wherein said nucleic acid sequence is not naturally associated with said cell in the collection. The cells are cultured under suitable conditions for expression of the polyclonal protein, which is obtained from the cells or culture supernatant. The present method is suitable for manufacturing recombinant polyclonal antibodies, thereby making available a superior replacement of plasma-derived therapeutic immunoglobulin products.

Abstract: The invention relates to a method for manufacturing recombinant anti-RSV antibodies and antibody compositions. The method comprises obtaining a collection of cells transfected with a collection of variant nucleic acid sequences, wherein each cell in the collection is transfected with and capable of expressing one distinct anti-RSV antibody. The cells are cultured under suitable conditions for expression of the anti-RSV antibody/antibodies. The nucleic acid sequence is introduced into the cells by transfection with expression vectors, which avoid site-specific integration. The present method is suitable for manufacturing recombinant mono- and polyclonal anti-RSV antibodies for therapeutic uses.

Abstract: The invention relates to methods for manufacturing drug products comprising at least two distinct members of a polyclonal protein, for example a polyclonal antibody, where each distinct member is expressed by a separate population of cells. The methods involve at least an initial step in which the cell populations expressing the distinct members of the polyclonal protein are cultured separately. The individual cell populations, or proteins expressed by the individual cell populations, are combined at a later point of the upstream or downstream processing to result in a single drug product comprising the distinct members of the polyclonal protein.
