  • set up 5ul ligations with plasmid, each of 6 promoters, plus one RBS.reporter
    • 0.5ul T4 ligase buffer
    • 10ng plasmid
    • 10ng RBS.reporter
    • 0.2ul promoter
    • 0.25ul T4 ligase
  • Incubate at room temperatures over lunch
  • pour plates (LB + amp + IPTG + X-gal)


  • Do quiz on units
  • Individual meetings with instructor to discuss final projects

    • use 100ul of cells and 2ul of the ligation mix
    • Leave on ice for 30 minutes
    • Heat shock for 45 sec @ 42C
    • Place back on ice
    • Add 300ul SOC
    • Incubate @ 37C for 30 min
    • plate entire transformation mix
  • Incubate at 37C
