An improved method for selecting a molecule such as an antibody, antigen, peptide, protein or fragment thereof and its encoding sequence, which molecule is expressed together with a phage coat protein on the phages surface. The improvement is achieved through a new mutant filamentous helper phage which has retained the gene III promoter, whereas the gene III encoding sequence is deleted. Amplification of phage titer of 10 6 times were achieved in M13-derived phages, when used for the selection of specific antibody. |
