OriT by Qu Mingzhi
mini-prep F-OriT_pEasy-T3
- using Transgen mini plasmid puriflication kit.
- 50µL after purflication
mini-prep electrophorsis result
- from left to right:
- mini-prep F-OriT_pEasy-T3-1
- mini-prep F-OriT_pEasy-T3-2
- marker (DL2000 Plus)
mini-prep double digesting test result
- Digesting F-OriT_pEasy-T3 with EcoR1/PstI.
- Digestion system contains:
1 µl 10*H 0.25 µl EcoRI 0.25 µl PstI 5 µl Plasmid 3.5 µl dH20 -------------------------- 10 µl Total
- 37℃ culutre for 3 hours.
- from left to right:
- mini-prep F-OriT_pEasy-T3-1 @ EcoRI/PstI
- mini-prep F-OriT_pEasy-T3-2 @ EcoRI/PstI
- marker (DL2000 Plus)
- marker (DL2000 Plus)
- I think the channel is bright enough for purification,so.... ^_^
Ori-T purification
- use Transgen kit.
- 30µL after purflication
electrophorsis result
- from left to right:
- purified F-Ori-T
- marker (DL2000 Plus)
Ligation:F-OriT ->pSB1A2
- Ligate the F-Ori-T fragment and pSB1A2 vector
- Ligation system contains (totally 10uL):3uL Ori-T, 2uL pSB1A2, 1uL T4-Ligase, 1uL 10Xbuffer, 3uL dH20
- 4℃ overnight
Lock & Key By Yu Tao
oriT Knock Out
- By Xu Anting
Competent cell test
- Transform pUC18 into three competent strains, and spread them onto Amp+ LB plates (with X-gal added).
- Set negative control as spreading strains without pUC18 onto Amp+ LB plates.
- Results: strain F has ~50 colonies, while R751 and pSC101 have 200+ colonies.
