  • New vectors: design new vectors for mammalian expression
  • Order oligos



New mammalian expression vectors MV9 and MV10

  • Use the Oligator tool to design oligo-assembly inserts for "MV6" (pcDNA3.1+ puro, mammalian transfection vector; CMV promoter)
    • MV9 - will carry Kozak-XbaI-NLS-6His-stop (Brady's and Behzad's project)
    • MV10 - will carry Kozak-XbaI-stop
  • Oligo assembly method will be used to make double stranded DNA with SpeI overhangs
  • Inserts will be ligated to XbaI cut MV6 to destroy the preexisting XbaI site
  • Clones will be screened for proper orientation and insert copy number

Oligator results:
