Making plasmids

  • PrepEase Endotoxin-Free Maxi Plasmid Kit, 78730 from USB

  • Streak cells on LB-30 µg/mL Kan or LB-amp 50 µg/mL (?)

  • Pick a single colony.

  • Inoculate 100 mL LB (+ 50 – 100 µg/mL ampicilin or 10 – 50 µg/mL kanamycin)

  • Shake overnight, 37C

  • Divide entire culture into 3 or 4 50-mL conicals

  • Use the appropriate rotor in the biochemistry floor model centrifuge.

  • Follow PrepEase directions, except: let filtrate drip directly into column (Steps 5-6)

  • Test in spectrophotometer at 1:500. Adjust dilution as needed

    • Abs 260
    • 260/280 ratio
