  • Publication number: 20160275238
    Abstract: Herein is reported a method for selecting or deselecting an antibody comprising a) determining for each Asp and Asn residue in an antibody Fv region the conformational flexibility of the C?-atom using a homology model ensemble, b) determining for each Asp and Asn residue in an antibody Fv region the size of the amino acid residue C-terminal to the Asp or Asn residue, and c) selecting an antibody in which the C?-atom is conformationally inflexible and/or the Asp or Asn has a big C-terminal amino acid residue, or deselecting an antibody in which the C?-atom has a moderate to high conformational flexibility and/or the Asp or Asn has a small C-terminal amino acid residue.

  • Publication number: 20160068602
    Abstract: Herein is reported a method for reducing the aggregation of an immunoglobulin in solution comprising the steps of i) comparing the amino acid sequence of the fourth framework region of the heavy chain of an antibody with a reference or germline sequence and determining whether one or more threonine residues and/or serine residues have been replaced by a different amino acid residue, and ii) modifying the amino acid sequence of the immunoglobulin by reverting the exchanged threonine residues and/or serine residues back to threonine or serine of the reference or germline sequence and thereby reducing the aggregation of an immunoglobulin in solution.

  • Publication number: 20150246961
    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.
