    摘要: A method of screening cell clones expressing a high yield of a polypeptide of interest is provided. The method employs the consecutive use of fluorescence activated cell sorting followed by colony picking based selection of cell clones with high expression rates and high proliferation rates. Furthermore, the invention pertains to a method of producing a polypeptide of interest using cells obtained by the described screening method.

    摘要: The present invention is based on the finding that the combination of a specific 5′UTR polynucleotide sequence (see SEQ ID NO 1) and the hCD33 secretory leader sequence in an expression cassette for expressing a polypeptide of interest results in a surprisingly better expression level of the polypeptide of interest compared to prior art expression cassettes. Based on this finding, the present invention inter alia provides novel expression cassettes, expression vectors and methods for producing a polypeptide of interest with high yield.

    摘要: The present invention inter alia pertains to a method for generating or selecting a eukaryotic host cell expressing a desired level of a polypeptide of interest, comprising: a) providing a plurality of eukaryotic host cells comprising a heterologous nucleic acid comprising at least one cassette (Cas-POI) comprising at least a first polynucleotide (Pn-POI) encoding the polypeptide of interest, at least one stop codon down-stream of the first polynucleotide, and a second polynucleotide downstream of the stop codon encoding an immunoglobulin transmembrane anchor or a functional variant thereof; b) cultivating the eukaryotic host cells to allow expression of the polypeptide of interest such that at least a portion of the polypeptide of interest is expressed as a fusion polypeptide comprising the immunoglobulin transmembrane anchor or a functional variant thereof, wherein said fusion polypeptide is being displayed on the surface of said host cell; c) selecting at least one eukaryotic host cell based upon the presence or amount of the fusion polypeptide displayed on the cell surface. Also provided are host cells, comprising respectively designed heterologous nucleic acids and methods for producing a polypeptide using respective host cells.
