Assemble pSB1C3_RecBCD-his

2018/06/11
Participants: Enikö Baligács
Protocol: Restriction digest, PCR purification, Ligation
Notes: digest with SapI SpeI

Prepare pSB1C3 backbone

2018/06/11
Participants: Dominic Schwarz
Protocol: Electrocompetent transformation, Mini Prep, Restriction digest, Agarose gel
Notes: template: pSB1C3-J04450 (iGEM BioBrick Kit plate 7 Well 23 O)
Results: agarose gel wasnt prepared properly leading to loss of samples. We decided to redo the experiment

Amplify Lac-Operon parts from pSB1C3 backbone

2018/06/11
Participants: Dominic Schwarz
Protocol: PCR, Agarose gel, Restriction digest
Notes: template: pSB1C3-J04450 (iGEM BioBrick Kit plate 7 Well 23 O)
Digests with: XbaI, SpeI and EcoRI, PstI for future assemblies
Lac Promoter: BBP_EcoRi_fw & LacO_XbaI_rv (57°C, 1min)
Lac terminator: Term_SpeI_fw & BBS_PstI_rv (65°C, 1min)
Results: see below

Assemble pSB1C3_lacO_RecBCD_lacT

2018/06/14
Participants: Dominic Schwarz
Protocol: Ligation, Chemical transformation, Mini Prep, Sequencing
Notes: template: pSB1C3-J04450 (iGEM BioBrick Kit plate 7 Well 23 O)
Digests with: XbaI, SpeI and EcoRI, PstI for future assemblies
Results: colonies but sequencing gave no results. We decided to test the PCR primer on a gel. Resequencing with VF2 and VR and blast analysis showed contamination with pBR322. After reevaluating the design of the plasmid with Thomas (supervisor) we realized there is an error. We redesigned the plasmid and plan to assemble it with gibson assembly.

Testing RecBCD Primers

2018/06/22
Participants: Katja Neishsalo
Protocol: Agarose gel,
Results: As expected all primers are ok :) PIC

Midi prep pSB1C3_mRFP

2018/07/31
Participants: Sophie von Schönberg, Ariane Krus, Franziska Winzig
Protocol: Midi Prep, Restriction digest, Agarose gel
Notes: we needed lots of backbone and linear DNA for other experiments, which is why we did this DNA preparation. obtained samples were controlled by restriction digest with KpnI, PstI : 500bp, 2672bp
