The pBAD expression system allows tightly controlled, titratable expression of your protein through the regulation of specific carbon sources such as glucose, glycerol, and arabinose. pBAD is ideal for expressing toxic proteins and optimizing protein solubility in E. coli. A selection of pBAD expression vectors are designed to facilitate cloning using Gateway® technology and TOPO® kits, protein purification, and detection.
