Method for Producing Proteins

摘要

This invention provides a method for obtaining a recombinant antibody with a desired function, comprising: (a) providing a population of antibody-forming cells suspected of containing at least one cell capable of producing an antibody exhibiting the desired function; (b) generating one or more transcriptionally active recombinant linear polynucleotides from the antibody forming cells obtained in step (a) wherein each transcriptionally active recombinant linear polynucleotide comprises a polynucleotide sequence encoding a variable domain of an antibody produced by an antibody-forming cell obtained in step (a) and one or more transcription regulatory elements; (c) expressing a recombinant antibody using one or more of the transcriptionally active recombinant linear polynucleotides generated in step (b); (d) screening the recombinant antibody produced by step (c) for the desired function; and (e) optionally repeating steps (b), (c) and (d) to identify a recombinant antibody exhibiting the desired function.
