Tandem Ori-T byMingzhi Qu, Ze Ren

2007-8-8 conjugation failure: Testing

  • test why R751 X Dh5α+pSB1A2(amp+) can grow on (Tc+/Amp+) & Dh5α+psc101(Tc+) X Dh5α+pSB1A2(amp+) can grow on (Tc+/Amp+).

Lock & Key by Yu Tao

Key1 & Lock 1 Efficiency Test

  • Add 1 mL overnight incubated sample culture of each group to 9 mL fresh LB.
  • Incubate them in 37℃ for 2 hours.
  • Divide the R0010.J23066(Key) and R0040.J23078.E0040.B0015-DH5a into 2 test tubes, add IPTG(finally 1uM) to only one of the two.
  • Culture all the samples overnight.
