Tandem OriT by Qu Mingzhi

transformation R-OriT & S-OriT

  • Use pEASY-3 as cloning vector .(Amp+)
  • tramsformation system contains :3uL R-OriT, S-OriT PCR product(after purflication), 1uL pEasy-T3
  • the Culture Dish(LB/Amp+) are trated with 5uL 1M IPTG & 40uL 40mg/mL x-Gal.
  • NEXT DAY: 10+ white cloney received.

Amplification Culture of E0240

  • select Positive E0240 Colonies from Plate,Culture in liquid LB,waiting for mini-prep.

Lock & Key By Yu Tao

R0010.J01008 and R0040.J01010 Digestion Product Purification

  • Use Transgen EasyPure PCR Purification Kit for R0010<-J01008 and Quick Gel Extraction Kit for R0040<--J01010.
  • 30uL per tube after purflication, one tube, respectively.

Electrophorsis Result

Double Digestion: R0040.J01010

  • Because the purified digestion product of R0040.J01010 is almost unseen in the electrophoresis result, I decide to redo it once more.
  • Digesting R0040.J01010 with EcoRI/SpeI.
  • Each digestion system contains:
4 µl       10*H
1 µl       EcoRI
