Conjugation Test:R751_pSC101 X Dh5α_psb1A2
- Donor: C600-R751_psc101 (Tc+)
- Recipient: Dh5α+ psb1A2 (Amp+)
- Control:
- donnor:C600_R751
- donnor:Dh5α_psc101
- mixing condition: 220rpm vs. 60rpm; 60min vs. 120min
- Day1:
- Get the plates from -4 fridge:C600-R751_psc101(Tc+), Dh5α_psb1A2(Amp+), C600_R751, Dh5α_psc101
- Amplification Culture in liquid LB for 12 hours.
- day 2:
- put 2mL of culture into 20mL of LB with antibiotics, sub-culturing.
