Ligation of self-build cloning site into pSBA3 (LS)
- aim of this ligation is to get our constructs into pSB1A3, so that they can be expressed more easily
- to distinguish between constructs in pSB1C3 and pSB1A3, those with the Amp- resistence will have an „A“ added after their name

Gibson for pIG15_403: checking plates (LS)
- lots of clones on the plates
- picked 8 clones
- incubation at 37°C in LB-Clm for ~8h (shaking)
Ligation: checking plates (LS)
- some clones on the ligation plates
- nothing on the ligation control plate :)
- picked 8 clones each (pIG15_803-8-A + pIG15_002-A)
- incubation in LB-Amp at 37°C for ~8 h (shaking)
Miniprep: all clones from Gibson plate (pIG15_403) and ligation plates (LS)

Test digest: HindIII + PstI
- 20µl digest, incubated at 37°C for 1h
- agarose-gel: nothing but smears…
- finally found out the reason: There was no RnaseA in buffer 1 of the biozym miniprep kit
- miniprep will be repeated tomorrow, test digest as well

Mini-Prep:
- pIG15_403 (8x), pIG15_803-A (8x) and pIG15_002-A (8x) are prepped with the Biozym-Kit
- according to the manufacturers protocol
- eluted in 50 µl H2O
