pMAL™-p5X Vector

As of June 30th, 2020, this product will be discontinued. It will be made available at Addgene.

The pMAL-p5X vector is designed to produce maltose-binding protein (MBP) fusions, where the protein of interest can be cleaved from MBP with Factor Xa protease (NEB #P8010). MBP fusions made with this vector include an N-terminal signal sequence, which directs the fusion protein to be localized in the periplasm.

  • The MBP has been engineered for tighter binding to amylose resin. 
  • Localization to periplasm can aid in protein folding and lead to higher yields of proteins containing disulfide bonds
  • Ampicillin resistance
