Patents Assigned to Unilever Patent Holding B.V.
  • Publication number: 20090286282
    Abstract: An expression library comprising a repertoire of nucleic acid sequences each encoding at least part of a variable domain of a heavy chain derived from an immunoglobulin naturally devoid of light chains and its use in producing antibodies, particularly fragments thereof, is disclosed. The invention provides a method for preparing antibodies, or fragments thereof, having a specificity for a target antigen which avoids the need for the donor previously to have been immunised with the target antigen.

  • Patent number: 7196187
    Abstract: An expression library comprising a repertoire of nucleic acid sequences cloned from a non-immunised source, each nucleic acid sequence encoding at least part of a variable domain of a heavy chain derived from an immunoglobulin naturally devoid of light chains (VHH) wherein the extent of sequence variability in the library is enhanced compared to the corresponding naïve expression library by introducing mutations in one or more of the complementarity determining regions (CDRs) of the nucleic acid sequences or by generating alternative combinations of CDR and framework sequences not naturally present in the naïve library repertoire. Also disclosed is the use of such a library in preparing antibodies, more particularly antibody fragments.
