  • Patent number: 12577293
    Abstract: Herein is reported a method for recombinantly producing a polypeptide in a cell comprising the step of cultivating a cell which comprises a nucleic acid encoding the polypeptide, and recovering the polypeptide from the cell or the cultivation medium, wherein each of the amino acid residues of the polypeptide is encoded by at least one codon, whereby the different codons encoding the same amino acid residue are combined in one group and each of the codons in a group is defined by a specific usage frequency within the group, whereby the sum of the specific usage frequencies of all codons in one group is 100%, and wherein the usage frequency of a codon in the polypeptide encoding nucleic acid is about the same as its specific usage frequency within its group.

  • Patent number: 11680110
    Abstract: Herein is reported a method for the humanization of non-human antibodies using a structure-based scoring matrix. With the scoring matrix it is possible to determine (the requirement for and) the suitability of specific (back)mutations of amino acid residues at defined positions of a selected human germline sequence. The scoring matrix takes into account the topology, the three-dimensional structure and the interactions of the respective residue and change. Thereby the influence on antigen binding of a specific amino acid residue change can be determined.
