- → The plates showed a low amount of colonies, and also red in the case of the positive plate.
- → The two plates with stripes of pZntR-GVP (pSB2K3) and pCueO-GVP (pSB2K3) culture for glycerol stocks showed growth and some single colonies.
- → All plates were stored in the fridge for further use.
Cultures
The overnight cultures with LB-amp100 medium of colonies E.coli TOP10 with
Plasmid isolation
Plasmid isolation was performed on the cultures of E.coli TOP10 containing the above mentioned plasmids with the "Sygma-Aldrich™ [http://www.sigmaaldrich.com/life-science/molecular-biology/dna-and-rna-purification/plasmid-miniprep-kit.html GenElute™] Plasmid Miniprep Kit".
- From each tube 5 to 10mL of culture was collected in a 2.0mL cup (tubes from pArsR-GVP, GVP and pNL29 were combined), and the cells were pelleted by centrifugation for 1 min. at max. speed and the supernatant discarded.
- Plasmids were eluted with 30μL MQ and stored in the fridge

HmtA no.3 | 42.6 | 1.91 | 2.06 | x | Yes (PstI) |
Restriction for Assembly, and Control (HmtA)
The plasmids from the o.n. precultures of pArsR-GVP and pSB2K3 (earlier last week) were cut with PstI and EcoRI to cut out the entire part between the pre- and suffix. The plasmids with PstI were cut with PstI for control.

pArsR-GVP | 13.0 | 3.0 | 3.0 | 1.0 | x | x | 1.0 |
pSB2K3 | 4.0 | 11.0 | 3.0 | 1.0 | x | x | 1.0 |

Purification
- → In step 7 the fragments were eluted in 12μL MQ and was stored on ice until use.

pArsR-GVP (E/P) | 36.1 | 1.91 | 0.17 | x | Yes (EcoRI/PstI) |
pSB2K3 (E/P) | 58.0 | 1.93 | 0.13 | x | Yes (EcoRI/PstI) |
Ligation
A total amount of vector of 100ng was used in a 1:3 ratio with insert.
- 3 uL Ligase buffer
- 1 uL T4 Ligase
- 9 uL MQ
- 4 uL plasmid pSB2K3 EcoRI/PstI
- 3 uL GVP restricted with EcoRI/PstI
Incubate:
- 25°C 50min.
- kept on ice for 10min.
Tranformation
- add 10uL of the ligation product to 50uL competent E.coli TOP10 cells.
Incubate:
- 30 min @ ice
- 90 sec 42°C
- 2 min @ ice
- add 800uL LB-medium
- incubate for 1 h at 37°C
- plate on LB-amp100 plates
- → Positive control was BBa_J61002-J23101 plasmid, and negative control was MQ.
