Abstract

A method for generating libraries of displayed peptides and/or antibodies (Abs) suitable for affinity interaction screening or phenotypic screening comprising: (i) obtaining selected library members comprising a displayed peptide and/or Ab and the corressponding polynucleotide (PN), or copies of it, (ii) pooling and fragmenting the PN, or copies of it, to form fragments, (iii) performing PCR amplification and thereby homologously recombining the fragments to form a shuffled pool of recombined PNs, which are not present in the selected library of (i).
