The Champion™ pET-DEST42 Gateway® destination vector is designed for rapid cloning with a Gateway® entry clone using lambda phage site-specific recombination and subsequent high-level prokaryotic expression controlled by the strong bacteriophage T7 promoter. Expression is induced by the production of T7 RNA polymerase in BL21(DE3) E. coli. The Champion™ pET-DEST42 destination vector offers:
  • Bacteriophage T7lac promoter for high-level expression
O operator sequences for lac repressor binding to ensure tighter regulation of transcription
  • pBR322 ori for minimal basal expression
  • C-terminal V5 and 6xHis tags for efficient detection and purification
R sites for efficient recombination with any attL-flanked Gateway® entry vector
