    摘要: The present invention provides a method for producing a polynucleotide sequence encoding an antibody variable domain, the variable domain comprising complementarity-determining regions (CDRs) located within a selected framework (the 'master framework'), the method comprising the steps of (a) providing at least one nucleic acid molecule encoding one or more CDRs and associated framework regions (the 'original framework'), (b) amplifying at least one CDR-encoding portion of the nucleic acid molecule(s) of step (a) using one or more pairs of oligonucleotides as amplification primers and (c) assembling a polynucleotide sequence encoding an antibody variable domain by combining the amplified CDR-encoding nucleotide sequences produced in step (b) with nucleotide sequences encoding said master framework, wherein the oligonucleotide primers of step (b) comprise nucleotide sequences which differ from the corresponding nucleotide sequences encoding said master framework. The invention further provides an antibody library, such as a phage display library, and methods of making the same.

    摘要: A library comprising variants of an antigen-binding template molecule, wherein (a) the antigen-binding template molecule does not specifically bind the epitope of interest but is known to specifically bind another epitope; (b) the antigen-binding template molecule has at least one of the following characteristics: (i) a predicted shape complementarity to the epitope of interest, (ii) a predicted physico-chemical complementarity to the epitope of interest, wherein it is predicted that upon mutation at least one amino acid residue position within the antigen-binding template molecule forms a chemical bond with an atom in the epitope of interest, or (iii) a predicted free energy of the interaction with the epitope of interest, as determined by computational methods such as but not limited to protein docking or free energy calculations; and (c) the variants have at least one residue comprising a substitution of an amino acid residue compared to the amino acid residue present in the antigen-binding template molecule.
