Cloning of CmR in pBluescript
Proceeding of the overnight ligations
- 8 transformation of the CmR overnight ligations
- 3 control transformation of Term1, CmR3 and pBluesript backbone
Proceeding of the minipreps from friday
- digestions of CmR in pBlue Miniprep to check for sequencing
- digestion with SacI, KpnI and EcoRI
- expected bands: 2859, 586, 272
- digestion with SacI, KpnI and EcoRI
- digestion with DraI
- expected bands: 1480, 1187, 692, 339, 19
- digestion with DraI
- Gel
- top:
- lane1-3: CmR1 (undigested, SacI/KpnI/EcoRI, DraI)
- lane4-6: CmR2
- lane7-10: CmR3a
- lane11-13: CmR3b
- bottom
- lane1-3: CmR4 (undigested, SacI/KpnI/EcoRI, DraI)
- lane4-6: CmR5
- lane7-10: CmR7
- lane11-13: CmR8
- according to the digestions we have the chloramphenicol resistance cassette in pBluescript
- Retrafo of CmR minipreps because we don't have enough DNA and unfortunately no glycerol stocks
- 3µl of CmR 1, 2, 3a, 3b
Cloning of CmR in standard plasmid
- PCR of CmR with CmR_prefix_fw and CmR_suffix_fw
25µl Phusion Master Mix 2x 1µl CmR_suffix_fw 1µl CmR_prefix_rev 1µl Maxiprep pBlue with insert (stock: ~200ng/µl, dilution: 1:20-->10ng) 22µl water ----- 50µl
PCR protocol 98°C 1min 98°C 10s | 61°C 10s | 26x 72°C 45s | 72°C 5min 4°C for ever
- Gel
- expected size: 851bp+43bp=894bp
- lane0:ladder
- lane1: CmR1
- lane2: CmR2
- lane3: CmR3a
- lane4: CmR3b
- lane5: CmR4
- lane6: CmR5
- lane7: CmR7
- lane8: CmR8
- cuted out CmR band and gel extraction kit
Cloning of cI in standard plasmid
- unwanted EcoRI restriction site in cI from geneart was mutated using standard protocol
- lane 1+2: mutated cI digested with EcoRI --> mutagenesis was succesfull
- maxiprep of this cI as well as J01003 in pSB1A2 were digested with EcoRI/PstI and XbaI/PstI to ligate this mutated cI in a standard plasmid (pSB1A2)
- lane 1-4: cI digested with EcoRI/PstI
- lane 5-9: cI digested with XbaI/PstI (lane 7 is ladder)
- lane 10+11: J01003 digested with XbaI/PstI
- lane 12+13: J01003 digested with EcoRI/PstI
--> digested cI and pSB1A2 backbone was cut out and ligated (15 min, RT) --> transformation in E.coli Top10 --> inoculation of liquid cultures --> miniprep --> send for sequencing and controll digest with EcoRI/PstI
- seqeuncing was succesfull
- digestion with EcoRI/PstI
- lane 1-6: mutated cI in pSB1A2 digested with EcoRI/PstI
results: sequencing and digestion pattern is correct
Tuesday, 10/07/08
Proceeding of cloning CmR in pBluescript
- a lot of single colonies of the transformation of the new ligations
- a lot of colonies on the retrafo
- inoculation of liquid culture of the 4 retrafos and the first 4 new ligations
- agar plates with new ligations are stored at 4 °C
Cloning of CmR in standard plasmid
- Digestion of CmR pcr product with PstI, XbaI
5µl NEB3 5µl BSA 10µl PCR product CmR (app. 50ng/µl (from gel) ) 1 µl PstI 1,5µl XbaI 32,5µl water
- 4 samples: 1,2, 3a, 3b
- 2h at 37°C
- PCR purification kit
- ligation of digested CmR pcr product in pSB1A2, 30min at room temperature
- transformation in TOP10, plated out on CmR plates
- ligation was done overnight as well
