Forming Oligodimers from Single-Strand DNA Chi6 Sequences

2018/07/31
Participants: Dominic Schwarz
Protocol: Oligodimerization
Notes: No notes.
Results: Double-stranded oligo nucleotides were stored for the experiments.

Assembling pSB1C3_Chi6 with A3 Assembly

2018/08/01
Participants: Dominic Schwarz
Protocol: Restriction digest, PCR purification, Gibson assembly, Chemical Transformation
Notes: Restriction digest with XbaI, SpeI-HF.
Results: No colonies.

Redo: Assembling pSB1C3_Chi6 with Ligation

2018/08/02 - 2018/08/06
Participants: Enikö Baliács
Protocol: PCR, PCR purification, Gibson Assembly, Ligation, Chemical transformation, Miniprep, Agarose gel
Notes: We performed linear amplification of Chi6 linear DNA stranded because assembly failed before. Gibson Assembly and ligation were performed in parallel.
Primer: BBS-PstI-rv
Results: Colonies were obtained but following colony-PCR showed no correct bands on the gel. The colonies had to be contaminants. Eni suspected errors during the PCR reaction.

Redo: Assembling pSB1C3_Chi6 with Ligation

2018/08/07
Participants: Enikö Baligács
Protocol: PCR, Agarose gel
Notes: Primer: BBS-PstI-rv
Results: No bands on the gel. Indeed, the error before occured during the PCR reaction. Thomas (supervisor) and Eni decided to give A3 assembly one more try.

Assembling pSB1C3_Chi6 with A3 assembly

2018/08/07 - 2018/08/09
Participants: Enikö Baligács
Protocol: Restriction digest, PCR purification, Ligation, Chemical transformation, Miniprep, Sequncing
Notes: We switched to the enzymes EcoRI, SpeI because we realized XbaI and SpeI had the same cutting sites and might lead to religation or false direction.
Results: We obtained colonies, however repeated sequencing with VF2 and VR didnt give successful reads.

PCR to Assemble pSB1C3_Chi6

2018/08/16 - 2018/08/20
Participants: Enikö Baligács
Protocol: PCR, Restriction digest, PCR purification, Ligation, Chemical transformation
Notes: Because oligodimerisation & ligation failed, we decided to amplify Chi6 by PCR; primers: Chi6_2clone & Chi6_fill
cycle: 98° 2 min; 98° 20 s; 57° 30s; 72° 20s (to 2 5 x) 72° 2 min; expect: ca 100 bp
Backbone: BBS_AgeI_Chi6_fw & BBP_SalI_Chi8_rv; AT: 62° expect: 2 kb
Next, we digested the samples with AgeI, SalI.
Results: Didnt work, Eni ordered 3 different primer pairs to stitch Chi6 together by PCR.

Preparing pSB1C3 Backbone

2018/08/30
Participants: Enikö Baligács
Protocol: Restriction digest, Agarose gel, Gel extraction
Notes: EcoRi & SpeI
Results: Obtained colonies following colony-PCR showed pSB1C3_Chi6 plasmids correct.

Dimerization of Short Chi Primers to Assemble pSB1C3_Chi6

2018/08/30 - 2018/09/05
Participants: Enikö Baligács
Protocol: Oligodimerization, Agarose gel, Gel extraction, Ligation, Chemical Transformation, PCR, Miniprep
Notes: The primers were stitched together and purified from Agarose gel. The samples were ligated into pSB1C3 and transformed into E.Coli NEB Turbo. The samples were tested by test-PCR via the primers VF2 and VR.
Results: Colonies. Consequent test-PCR proved the correctness of pSB1C3_Chi6. (PIC)
