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
