  • Publication number: 20200216880
    Abstract: Herein is reported a method for selecting a variant of a parental antibody variable domain encoding nucleic acid, wherein the parental antibody variable domain amino acid sequence encoded by said encoding nucleic acid has at least one developability hot spot, the method comprising the steps of (i) providing a multitude of DNA-containing samples (genomic material of antibody secreting B-cell) each including one or more antibody variable domain encoding nucleic acids; (ii) performing PCR amplification of said antibody variable domain encoding nucleic acids of (i) using consensus sequence-specific primers to obtain amplification products (wherein said consensus sequence-specific primers bind to consensus sequences that are common to a plurality of genes within the genetic loci set, thereby generating a pool of amplification products); (iii) sequencing a plurality of said amplification products obtained in step (ii) in order to determine the relative proportion of each nucleotide at each position in a sequencing

  • Patent number: 10047162
    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a reference or germline sequence and determining whether one or more threonine residues and/or serine residues have been replaced by a different amino acid residue, and ii) modifying the amino acid sequence of the immunoglobulin by reverting the exchanged threonine residues and/or serine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.
