- First, I have to say sorry because I upload the previous experiment records to our notebook so late. But late is ever better than never, right. n_n--Tao Yu 08:00, 9 August 2007 (EDT)
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+).
colony PCR Test for R751, pSC101(I)
- Test Lb- R751 plate, Lb- pSC101 have the correct plasmid.
- Test plate:LB- R751, Lb- pSB101, Amp+ Dh5α-R0040(as control), R751 plasmid, pSC101 plasmid.
- primer :R751 OriT primer, pSC101 primer.
- according to <Count:Colony PCR STANDARD PROTOCOL>

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.
