  • Vector backbone
  • Backbone manufacturer
  • Modifications to backbone
    pKD is derived from pKK223-3 (Pharmacia). The ampicillin (Amp) resistance gene was replaced with a kanamycin (Kan) resistance gene. The original multiple cloning site (MCS; NcoI-EcoRI-SacI) was modified by adding an additional ribosome binding site (RBS) and a second MCS (NdeI-BamHI-SalI-HindIII), thus enabling simultaneous protein expression from two genes, both under the control of the same tac promoter.
