pADL-10b

Technical Description

pADL™-10b is a phagemid vector designed for phage display on the filamentous bacteriophage M13 or equivalent. This vector contains a PelB leader sequence followed by a full-length copy of the gene III sequence and a double-SfiI cloning site to introduce foreign polypeptides on the N-terminal side of the gene III protein. Expression of the fusion is under the tight control of a lac promoter. A strong transcriptional terminator upstream from the promoter efficiently represses undesirable expression and prevents promoter leakiness in absence of induction, thus limiting negative selection against clones bearing toxic products. The absence of amber codon before the gene III results in strong display (Fig. 1).

Applications

  • Phage display at the N-terminal side of gene III protein of the filamentous bacteriophage.

  • scFv display.
