pADL-20c

Technical Description

pADL™-20c is a phagemid vector designed for phage display on the N-terminal side of the protein III of the filamentous bacteriophage M13 or equivalent. This vector contains a PelB leader sequence for expression in the periplasm, a double-SfiI/BglI cloning site to introduce scFvs or Fab fragments, a HIS tag for purification and an amber codon located before the full-length copy of the gene III sequence. On non-suppressive bacterial strains, free scFvs or Fab fragments are produced in the periplasm where they can be assayed for binding or purified for further testing. Expression of the fusion is under the control of a lac promoter that has been adjusted at a level comparable to the widely used phagemid pCOMB3.

Applications

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

  • scFv and Fab display.

  • Free scFv or Fab expression.

For research use only; not intended for any animal or human therapeutic or diagnostic use.
