Transformation
Investigator: Christian
Aim: Preparation of BioBrick templates → Transformation into E. coli DH5α.

Transformation of 1 µl pPha-NR, 1 µl pPha-T1 and 1 µl pCAT (diluted 1:3 with bidest. H2O) in E. coli DH5α (30 min ice, 90 sec 42°C, 1 min ice, 45 min 37°C + 1 ml LB), plated on LBamp, overnight at 37°C.

21.03.2013

Inoculation
Investigator: Christian
Aim: Preparation of BioBrick templates → Inoculation of transformants for miniprep.

2 colonies of pPha-NR and pPha-T1 inoculated in 5 ml LBamp, overnight at 37°C.

pCAT is a cosmid, transformation failed.

22.03.2013

Miniprep
Investigator: Christian
Aim: Preparation of BioBrick templates → Miniprep of the template-plasmids.

Miniprep of the liquid cultures (QIAprep Spin Miniprep Kit (Qiagen)), eluted in 25 µl bidest. H2O.

Digest
Investigator: Christian
Aim: Preparation of BioBrick templates → Control digestion of the template plasmids.
  • 3 µl DNA template
  • 1 µl enzyme 1
  • 1 µl enzyme 2
  • 4 µl buffer 2
  • 31 µl bidest. H2O

Samples:

PCR
Investigator: Christian
Aim: Construction of BioBricks → Amplification of iBB2 via PCR.

PCR on CAT-cassette (iBB2):

Volume Reagent   Temp (°C) Time
1 µl Q5 Polymerase   95 3 min
1 µl Primer fw (1pmol/µl)   95 30 sec
1 µl Primer rv (1pmol/µl)   65 30 sec x26
